version.sh: output short mc git version to prevent full rebuild.

When using exact git version in AC_INIT, every git commit result in different
AC_PACKAGE_VERSION and AC_PACKAGE_STRING macros at config.h
Hence this will cause a full rebuild (see #2252).

4.8.26-217-ge819ed742 -> 4.8.26-git
4.8.27-pre1-1-gcbc214da8 -> 4.8.27-pre1-git

TODO: tests needed for final version release workflow!
