dev-install: use profile stacking instead of copying files

Instead of duplicating /etc/portage/ into /usr/local/etc/portage/, use
the parent profile to let portage stack /usr/local/etc/portage/ on top
of /etc/portage/ dynamically.  This avoids confusing duplication and
takes care of the simple file that gmerge has been installing.
