selftests: forwarding: Fix race condition in mirror installation
When mirroring to a gretap in hardware the device expects to be
programmed with the egress port and all the encapsulating headers. This
requires the driver to resolve the path the packet will take in the
software data path and program the device accordingly.
If the path cannot be resolved (in this case because of an unresolved
neighbor), then mirror installation fails until the path is resolved.
This results in a race that causes the test to sometimes fail.
Fix this by setting the neighbor's state to permanent in a couple of
tests, so that it is always valid.
