fix(profiles): Go back to the stable portage version

sys-apps/portage-2.1.12.2 is now stable which is new enough for us.
fix(coreos-overlay): Fix improper EAPI declarations

EAPI needs to be the first thing in an ebuild. This clears up useless
errors from tools scanning the tree like emirrordist.
fix(coreos-overlay): Add missing or fix incomplete Manifests

emirrordist will refuse to handle files that are not included in the
Manifest file. To keep things happy just sweep across the tree adding
them. (A lot of these packages could actually go away, but that is a
different project for another day).
fix(mobile-broadband): Remove workaround for bug that doesn't exist

Fix the last of the bogus errors in the coreos overlay, removing this
hack makes the SRC_URI lines valid again and all tools are happy now.

Fix digests
fix(config): Switch distfiles mirror list to our own

These two mirrors are generated specifically from our own overlays so
they should always include everything we need. The default Gentoo mirror
is provided simply as a sane backup.

make docker run directly under systemd without forking

Docker seems to be working fine now under systemd. Some recent code
changes have fixed the problems we were running into before.

What has been tested while running docker directly under systemd:
1. docker run
2. docker pull
3. docker images
4. docker rm

fix(sys-kernel/coreos-kernel) bump kernel version to 3.9.8

Pull in all of the good fixes, especially in the networking area, that
the 3.9.8 kernel provides.
bump(net-misc/gsutil): Bump gsutil to version 3.31, add dependencies

This includes a new gsutil verison which is not yet in upstream portage
along with new ebuilds for a couple of its dependencies that are also
not in portage:
    dev-python/google-api-python-client
    dev-python/socksipy-branch

Also, dev-python/python-gflags is included here to apply two extra
patches that fix some unit tests and add mark that it conflicts with the
old version of dev-cpp/gflags that we had been using up until now.

Hopefully all this will be merged upstream soon:
