version.sh: fix git rev. generation (.git is not always a directory)

It appears git submodule handling recently changed, changing the .git
directory to a regular file containing submodule specific information.
This means that version.sh would generate "#define VERSION "git-UNKNOWN""
if the checkout is a submodule, because it explicitly checks for a .git
directory using test -d. Change it to -e so that this case is handled
correctly.
