More aggressively inherit pgrps from parent jobs

Browse Source 
Prior to this fix, a job would only inherit a pgrp from its parent if the
first command were external. There seems to be no reason for this
restriction and this causes tcsetgrp() churn, potentially cuasing SIGTTIN.
Switch to unconditionally inheriting a pgrp from parents.

This should fix most of #5765, the only remaining question is
tcsetpgrp from builtins.
