chg: allows default hg path to be overridden

Before this patch, chg will fall back to "hg" if neither CHGHG nor HG are set.
This may have trouble if the "hg" in PATH is not compatible with chg, which
can happen, for example, an old hg is installed in a virtualenv.

Since it's very hard to do a quick hg version check from chg, after discussion
in IRC with smf and marmoute, the quickest solution is to build a package with
a hardcoded absolute hg path in chg. This patch makes it possible by adding a
C macro HGPATH.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install:

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing:

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.
