Put version info into /etc/os-release

We will use these data for showing meaningful and (mostly) accurate
version information via NETCONF, eventually.

I a;sp want the version info to be visible in actual binaries as well,
so let's instruct Buildroot to keep .git around. That is not as simple
as, e.g.:

 CLA_SYSREPO_OVERRIDE_SRCDIR_RSYNC_EXCLUSIONS = --include .git

...because in the CI setup, these directories are already git submodules
of something, and therefore their .git uses a relative path, and one
cannot easily copy it around. Instead, query the actual original path
and put the result into a new .gitdir file. That should work on both the
CI system and a random developer's setup which might not be using
submodules for projects they are working on.
