setup: prevent setuptools from laying an egg

Previously, test-hghave.t was failing on Windows (and on Linux if
$FORCE_SETUPTOOLS was set) with the following:

  --- c:/Users/Matt/Projects/hg/tests/test-hghave.t

Augie relayed concerns[1] about the first attempt at this, which also excluded
'install_egg_info'.  All that needs to be excluded to avoid the egg and make the
test work is to filter out 'bdist_egg'.  (Actually, the body of this class could
simply be 'pass', and 'bdist_egg' still isn't run.  But that seems to magical.)

Also note that prior to this (and still now), `make clean` doesn't delete the
'mercurial.egg-info' that is generated by `make install`.
