feat(sys-apps/baselayout) CoreOS deserves it's own etc/os-release

Also modifies /etc/gentoo-release because python hasn't been updated to
use os-release, it still wants the old distro-specific files.
feat(sys-apps/baselayout) remove old baselayout ebuild

It wasn't being used, portage-stable was more up to date anyway.
feat(sys-apps/shadow) delete ebuilds

We are using the newer one in portage-overlay, these are here for no
reason, so delete them.
feat(sys-apps/module-init-tools) delete

We are using kmod instead, so just delete module-init-tools entirely,
it's not needed.
feat(sys-apps/debianutils) delete

The ebuilds in portage-stable are newer, if we are even still using this
package (I wasn't able to tell for some odd reason...)
fix(app-editors/qemacs): Fix malformed patch.

This patch uses relative paths that are rejected by newer and stricter
eclass versions. Pulled from current portage but I'm purposefully *not*
updating the ebuild as the latest texi2html which in turn pulls in a lot
of new perl dependencies and we don't even care about texi2html or the
html docs it is used to produce in the first place so bleh.

Merge pull request #69 from marineam/eclass-fixes

fix(app-editors/qemacs): Fix malformed patch.
fix(coreos-base/verity): Fix use of gcc flag not available in 4.6

Verity uses -fstack-protector-strong which was added in 4.7, use -all
instead which is available in 4.6. Dunno what impact this has but we
don't actually use it yet so *shrug*. Only a temporary fix since we
would probably want to fork verity if we use it or drop support entirely
if we decide we never will.
