PSMake.pm: support extracting package version from git

This adds a new function, pick_git_version(), which attempts to extract
the package version from git.  In addition, pick_version() is renamed to
pick_dir_version() and replaced by a wrapper which tries first git and
then the traditional directory method, and pick_package_and_version() is
enhanced to try git before falling back to 'head' or an unknown version.

Version extraction from git works best when the stem has _not_ already
been modified (e.g. by code in ~/.psmake) to include the version.
