There are several test cases still using exit 0 when they need to be skipped. Use kselftest framework skip code instead so it can help us to distinguish the proper return status.

Criterion to filter out what should be fixed in selftests directory: grep -r "exit 0" -B1 | grep -i skip

This change might cause some false-positives if people are running these test scripts directly and only checking their return codes, which will change from 0 to 4. However I think the impact should be small as most of our scripts here are already using this skip code. And there will be no such issue if running them with the kselftest framework.

V2: router_mpath_nh.sh and outer_mpath_nh_res.sh sources lib.sh, there is no need to assign ksft_skip value in these two.
