[F-OEM-5.6][SRU][PATCH 1/2] selftests: pmtu.sh: use $ksft_skip for skipped return code

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.
