LU-17986 tests: Update sanity-lnet 111 for IPv6

Modify test_111 to use setup_router_test() so that it will use
IPv6 NIDs for the --gateway argument when that is what the test
environment has configured.

The test is also modified to check success/failure of the route add
command, and to verify that the correct number for routes were added.
