Subject: recursedeps: include cyclic dependencies
Cyclic dependencies (A depends on B, B depends on A) were not selected
because neither package could be removed individually, so
can_remove_package would always return false for both. By preselecting
all dependencies then filtering back out any dependencies still required
by any packages that will not be uninstalled, groups of unneeded cyclic
dependencies can be found.
Fixes FS#41031
