Enable fib-onlink-tests.sh and msg_zerocopy.sh in kselftests/net on Bionic

[Po-Hsu Lin]

[Impact]
Found this issue while debugging missing tests with bug 1934282.

On Bionic there are 3 scripts that are not in the Makefile of the kselftests/net:
$ for file in $(ls *.sh); do grep -q $file Makefile || echo $file; done
fib-onlink-tests.sh
in_netns.sh
msg_zerocopy.sh

[Fix]
* 830669e691464c selftests/net: enable msg_zerocopy test
* 1751eb42ddb56b selftests: net: use TEST_PROGS_EXTENDED
* a52b839752aab7 selftests: Add fib-onlink-tests.sh to TEST_PROGS
* Set fib-onlink-tests.sh as executable

They all need to be backported to Bionic.
For the in_netns.sh it's not causing any issue to us when being called by run_afpackettests, but I think it's no harm to fix it to reduce confusions. Commit 1751eb42ddb56b will replace the change in 9faedd64 selftests: net: add in_netns.sh TEST_GEN_PROGS_EXTENDED [1] and 5ff9c1a3 selftests: net: add in_netns.sh to TEST_PROGS [2], and since we need to backport it there is no need to work on these two.

[2] https://github.com/torvalds/linux/commit/5ff9c1a3dd92

[Test]
Run the "net" test suite in the kselftest directory from a patched source tree. fib-onlink-tests.sh and msg_zerocopy.sh tests will be executed.

[Where problems could occur]
This change will bring in more test for our SRU, we might see new failures because of these test in the future.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
