packaging: extract pre-computed version when running from plain tarball The tarballs created by setup.py are not including the usual archive markers that `hg archive` leaves, so the rewrite of the version number computation actually left the empty version string around. This meant that installations from PyPI would use 0.0.0 as version string. Differential Revision: https://phab.mercurial-scm.org/D10502
