packaging: adapt `__version__.py` parsing for `setuptools_scm` output

The file is now generated by `setuptools_scm`, which stores values as strings
with strong quotes.  This avoids the following failure at the end of the Inno
installer build:

        Exception: could not parse c:\Users\Matt\projects\mercurial\mercurial-devel\mercurial\__version__.py

Note that non-tagged builds end up with complex version strings, and include
characters that WiX rejects.  That's probably fine- we don't do nightly or other
non-tagged builds for installers.

Also note that while the Inno installer is capable of using this version string
as part of the installer, the WiX installer is not for some reason.  That
installer needs to be built with `--version VERSION` to inject the version into
the installer metadata and the filename.
