dnf: Fix /var package cache directory check in package_subdirs()

package_subdirs() receives the full cache directory path, not the
configured package cache directory (something like /var/cache/libdnf5),
so we fix the check to check if the parent directory of the given
cache directory is /var/cache so we don't have to know whether the
last component is dnf or libdnf5.
