Drop explicit file listings

After some subpackages have been merged/dropped, the file listings were
only used to filter out hgk. That was overly complex. It is simpler to
just be explicit.

This also fixes the hgk .pyc not being packaged together with the .py
file.

This change was isolated and documented (and obfuscated?) by Mads Kiilerich.
