readme: mention how to run in-place

The README describes how to install Mercurial but it does not describe how to
run it in place (for developers). This adds a short paragraph to the README
describing how to do run Mercurial inplace.

#!/usr/bin/env python

import errno, os, sys

for f in sys.argv[1:]:
    try:
        print f, '->', os.readlink(f)
    except OSError, err:
        if err.errno != errno.EINVAL:
            raise
        print f, 'not a symlink'

sys.exit(0)
