Use .tar.bz2 for "make dist" instead of .tar.gz

Mercurial's tgz archiver is writing the full output path into the archive,
 causing things like 7-zip to uncompress it to
 "Users/icculus/projects/physfs-2.0.2.tar" instead of just "physfs-2.0.2.tar".

It seems reasonable to believe everyone has .tar.bz2 support by now anyhow.
