fetchMercurial: set HGPLAIN when invoking hg

Browse source 
Without setting HGPLAIN, the user's environment leaks into
hg invocations, which means that the output may not be in the
expected format.

HGPLAIN is the Mercurial-recommended solution for this in that
it's intended for uses by scripts and programs which are looking
to parse Mercurial's output in a consistent manner.
