[G][SRU][PATCH 1/2] selftests: pmtu.sh: use $ksft_skip for skipped return code

Mon May 24 06:58:41 UTC 2021
BugLink: https://bugs.launchpad.net/bugs/1887661
This test uses return code 2 as a hard-coded skipped state, let's use
the kselftest framework skip code variable $ksft_skip instead to make
it more readable and easier to maintain.
