efi: drop -signed subpackages

We chose to provide methods to sign packages but to avoid
signing these by default (with some arbitrary test keys)
the signatures are being added *after* the build by means
of rpmrebuild-pesign; all of this is made significantly
more complicated if there are separate -signed subpackages.

So these are being dropped in the packages; account for that.
efi: add use/efi/memtest86

It's implemented just like EFI_SHELL and will definitely
change someday but so far it's like this...
regular.mk: use/efi/memtest86 for regular-rescue

It's proprietary now but still very useful with no free software
alternatives for UEFI platform so far; let's include efi-memtest86
into the rescue image at least.
efi: add pesign to the rescue

It's at least as worthy as sbsigntools are.
desktop+regular: added synaptics setup for tap clicks

Thanks sem@ for implementing and announcing wrt Simply 7.0.2.
regular+kde4: added quick-usb-formatter

Thanks zerg@, it's been one of the things asked for.
Should end up in kde4-regular dependencies if OK.
desktop+e17+e18+extra: include "e18"

I wondered how regular-e18 lacked econnman but it only
took a closer look to understand that it's just not told
to go in, plain and simple!

There are no e18-extra-modules (at least so far),
confine that to desktop+e17.
regular.mk: use installer-distro-altlinux-desktop

...instead of installer-distro-desktop which pulls in
alterator-auth which breaks things big time for sysv-tde
installer image due to avahi-daemon lazy to run.

Of course it's the last step of installation that has to fail.

And I've been considering this for several months already anyways.
