Update setup.py to identify the version when not ran in a repository.

setup.py only identifies the correct version when ran within a repository.  For
source tarballs, this results in an incorrect version being reported and used
for creating release packages, like RPMs.

To fix this, try to get the version from mercurial.util.version() when not in a
repository before defaulting to "unknown".
