util/genbuild_h: Add gitfile support

`genbuild_h.sh` checks whether it is running from a coreboot's own git
worktree to decide wheter to use git as the time source. This check
fails when `${top}/.git` is a gitfile, e.g. when coreboot is a
submodule.

Add a proper `git rev-parse` call to check the condition.
