Disabled hginstallscripts @LIBDIR@ replacement in setup.py.

setup.py replaces @LIBDIR@ in the hg script, with a path that differs between
Python versions.
libdir in hg doesn't need to be set if mercurial is available in the public
namespace, as it is in Debian.
hg doesn't alter sys.paths if this replacement hasn't happened.

test: make test-doctest.py work when it's not run from a mercurial repo

This assumption fails when building and running tests from a source
tarball, e.g.
