selftests: hsr: Add ping test for PRP 



Add a selftest for PRP that performs a basic ping test on IPv4 and IPv6,
over the plain PRP interface and a VLAN interface, similar to the existing
ping test for HSR. The test first checks reachability of the other node,
then checks for no loss and no duplicates.
