build: don't clean __version__.py on 'make clean' in release tarballs

When running 'make clean' in an extracted release tarball, file
mercurial/__version__.py is removed, causing a subsequent install to
indicate 'version unknown'.

This problem was reported in the past [1] and a patch proposed in that mail,
but was never properly sent nor applied.
