aiju found a bug in port/sysproc.c sysrfork(). in the
RFPROC|RFNOMNT case, it sets up->pgrp->noattach
instead of p->pgrp->noattach setting the *parents*
noattach flag instead of the childs pgrp.

small additional note. RFPROC|RFNOMNT alone makes no difference
of course as parent and child will share the same pgrp. but
with RFNAMEG or RFCNAMEG it makes a difference.
the number of programs that use this combination is probably
very small. it was triggered with irc7 which is not part of
the plan9 distribution.
