sommelier: init at 78.12499.0.0-rc1

sommelier has a lot of dependencies on other Chromium OS packages.  To
manage this mess, I introduced chromiumOSPackages to hold them all,
since most of them won't be useful aside from building other
Chromium OS packages, and chromiumOSPackages.common-mk, which is a
wrapper around stdenv to handle interacting with Chromium OS's
idiosyncratic GN-based build system.

I adapted crosvm's updateScript to become the updateScript for all of
chromiumOSPackages, and pulled crosvm under chromiumOSPackages.  This
means that all Chromium OS packages use approximately the same
versions that are distributed as an upstream release.

There are still a couple of Chromium OS packages in Nixpkgs that
aren't part of this set.  Pulling those in is future work.

+Subject: [PATCH 03/10] common-mk: don't leak source-absolute paths
+
+Source-absolute paths like //vm_tools/whatever were being leaked to
+subprocesses, which of course didn't know how to understand them.
+With this patch, source-absolute paths are only used to tell GN the
+outputs, and normal Unix paths are passed to subprocesses.
