Fix and cleanup orphan package support
Fix and cleanup orphan package support

Avoid setting port specified with -r option as non orphan, and make
sure that in `portmaster -o port2 port1` orphan flag is always passed
by port1 to port2, even when port2 is already installed.

Meanwhile, remove the reference to pkg autoremove, as it's different
from portmaster -s.
