selftests: forwarding: Fix ping failure due to short timeout
[ Upstream commit e4137851d4863a9bdc6aabc613bcb46c06d91e64 ]
The tests send 100 pings in 0.1 second intervals and force a timeout of
11 seconds, which is borderline (especially on debug kernels), resulting
in random failures in netdev CI [1].
Fix by increasing the timeout to 20 seconds. It should not prolong the
test unless something is wrong, in which case the test will rightfully
fail.
