i18n: lookup .mo files in private locale directory

This default is to look for /usr/share/locale/xx/LC_MESSAGES/hg.mo for
language xx, but this code will instead do the lookup from locale or
mercurial/locale relative to the root of the Mercurial source tree.

Updated setup.py to ship the xx.po and xx.mo files.
