resourceutil: correct the root path for file based lookup under py2exe
This silly copy/paste error caused "Mercurial" to be truncated from
"C:\Program Files". The fact that "helptext" and "defaultrc" are now in a
subpackage of "mercurial" added it back on, and everything seemed to work. But
that broke if not installed to the default directory, and also caused TortoiseHg
to look at Mercurial's config files instead of its own.
