selftests: net: lib: Add several autodefer helpers
Add ip_link_set_addr(), ip_link_set_up(), ip_addr_add() and ip_route_add()
to the suite of helpers that automatically schedule a corresponding
cleanup.
When setting a new MAC, one needs to remember the old address first. Move
mac_get() from forwarding/ to that end.
