bump(sys-kernel/bootengine): Updates for new dracut version

Dracut is now in portage-stable and DRACUT_MODULES is unused.
Update bootengine dependencies so we can use btrfs and mdadm in the
initrd. Drop kbd because I'm excluding out the terminfo module now.

maint(sys-apps/systemd): Sync patches with upstream

Upstream has merged all of our reload bug fixes, replace local patches
with the upstream versions.

Drop the patch that removed the check for /etc/os-release. We always
initialize missing files in the initrd so it isn't needed any more.
fix(profiles): Move CFLAGS, remove -g, add -mtune=generic

Slowly moving make.conf into profiles, here is another piece. We never
actually use the built debug information so remove -g to produce a
little less of it. Add -mtune=generic to let GCC optimize for whatever
it thinks the most common processors are.
fix(profiles): Enable ipv6 globally because WTF DUH!

chore(app-emulation/docker): remove symlink-usr case

We are never shipping another -generic image so just make symlink-usr
the only .service file.
fix(app-emulation/docker): add TMPDIR=/var/tmp
