As Xen uses git as primary repository, get git commit id for
xen_changeset info.

Changes in v2:
 - split scm calls into separate script - based on Linux kernel one,
   with tags handling removed

Changes in v3:
 - do not assume tools/scmversion started from the repository toplevel
   dir - it is actually called from xen/ subdir
