x11: make use/x11/xorg arch-dependent

There's no such thing as xorg-dr[vi]-intel on non-x86 AFAIK,
and the rest of the videodrivers is only generic on x86 too.
armh: get rid of 50-sshd-root

It was a temporary hack actually, and is better dropped long-term:
things like predefined root accounts with remote access are *evil*
and this hook was a half of that "solution".

Use of oem feature to integrate first-boot setup is recommended
to deal with this issue, at least when graphics are available.
desktop+gvfs: factored out from lxde pkglists

gvfs pulls gnome-online-accounts and dconf in;
these add considerable bloat that well may be
undesirable in a lightweight distro, just pull
this into a separate pkglist.
regular.mk: get gvfs back into lxde flavour

aen@ has suggested that gvfs support be present in regular-lxde
as pcmanfm2 can make use of it; let's factor it back in here.
clean.mk: allow to forbid cleanup explicitly

The behaviour that sort of settled didn't actually follow
the principle of the least surprise when one really wanted
to have BUILDDIR available for inspection; DEBUG=2 would be
effective to achieve that but CLEAN=0 would not.

Thanks led@ for spotting and reporting this.

armh.mk: *fix* nexus7 aliases

So the autobuilds were failing for these two weeks since
commit e43386c1fe0eaf4e0b49508ec7b16379063a5707 was *totally*
braindead: there's no "arm-e17" target neither "arm-kde4" one.

Fixed while awake and adjusted (in sync with build node)
to reference particular nexus7 and not just "arm".

The sad thing is that it should now read "nexus7old" TBH,
2013 model is not Linux friendly at all at the moment...
p7.mk: add regular-server bridge

This proxy makefile is still needed unfortunately...
power: employ services feature

rootfs got handy either though managing modules to preload
might be enhanced further.
init: we don't need no systemd with sysvinit

That is, no need to pull in systemd as syslogd-daemon provider
when an unspecified one has been requested by interactivesystem
or anything else.

The tricky issue is that THE_LISTS will get expanded separately
and too late to specify a particular provider which will have been
auto-chosen while expanding e.g. BASE_PACKAGES.
ve.mk: employ init feature

It should actually work better than manual specification
now that it's fixed.
ve.mk: tweaked ve/generic

etckeeper was suggested by george@ along with vim-console;
the latter should come by server,base tags but so far does not
(splitting server-base list into common, bare metal and virtualized
parts in haste looked suboptimal).
p7.mk: ve/altlinux-p7 bridge

This one adds another image class as well.
Hope this kludge will not get self-conscious...
ve.mk: use/repo for ve/generic

Setting up apt configuration in every container
is pretty annoying, let's enable it by default.

Some provision to add/enable local mirror would
be beneficial but not there yet...
