configure: Allow to detect git checkout if .git is not a directory

E.g. if you use openvpn as a git submodule, it can be a
file that points to the parent's git directory.

The changes to Makefile.am are not strictly required, they
still work with that case, but I wanted to keep the usage
consistent.
