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 Signed-off-by: Andrew Gregory <andrew.gregory.8@gmail.com> Signed-off-by: Allan McRae <allan@archlinux.org> (cherry picked from commit 6ac2ee21b30f3c5f331d19349f96bb8e5b020b47)
