After PDEPENDs have been neglected by the find_smallest_cycle function,
do not try to merge them too early if they are already satisfied by
an installed package. This fixes incorrect merge order for PDEPEND
cycles involving xorg-server and xorg-drivers, which was triggered
by commit 5095c2023595a75e2848f1ad3dbe25b5fb451a44 because it gave
PDEPEND higher priority than satisfied buildtime dependencies.
Fixes: 5095c2023595 ("find_smallest_cycle: enhance search prioritization")
