selftests: fib_tests: mute cleanup error message

commit d226b1df361988f885c298737d6019c863a25f26 upstream.

In the end of the test, there will be an error message induced by the
`ip netns del ns1` command in cleanup()

  Tests passed: 201
  Tests failed:   0
  Cannot remove namespace file "/run/netns/ns1": No such file or directory

This can even be reproduced with just `./fib_tests.sh -h` as we're
calling cleanup() on exit.

Redirect the error message to /dev/null to mute it.

V2: Update commit message and fixes tag.
V3: resubmit due to missing netdev ML in V2
