Commit b9d5f5711d ("selftests: net: increase the delay for relative
cmsg_time.sh test") widened the accepted value range 8x but we still
see flakes (at a rate of around 7%).
Return XFAIL for the most timing sensitive test on slow machines.
Before:
# ./cmsg_time.sh
Case UDPv4 - TXTIME rel returned '8074us - 7397us < 4000', expected 'OK'
FAIL - 1/36 cases failed
After:
# ./cmsg_time.sh
Case UDPv4 - TXTIME rel returned '1123us - 941us < 500', expected 'OK' (XFAIL)
Case UDPv6 - TXTIME rel returned '1227us - 776us < 500', expected 'OK' (XFAIL)
OK
