[release-4.14] denylist: add dhcp-propagation and podman.rootless-sys…

…temd

In 4.14, these tests are using the F38 container. The F38 content was
moved to the archive on the mirrors but the metalinks still reference
the non-archive URLs causing these tests to fail.

Let's denylist them for now until https://pagure.io/releng/issue/12204
is resolved.
