[SeaBIOS] [PATCH] fix buildversion.sh

[Gerd Hoffmann]

Recent git versions place the submodule git repos into the
.git/modules directory of the toplevel repo.  In that case
.git of the seabios tree isn't a directory, but a regular
file, saying where the gitdir is.

Extent the git check to also allow .git being a regular file,
so buildversion.sh works correctly when called within the qemu
submodule.
