selftests: net: don't access /dev/stdout in pmtu.sh

Browse source

When running the pmtu.sh via the kselftest infra, accessing
/dev/stdout gives unexpected results:
  # dd: failed to open '/dev/stdout': Device or resource busy
  # TEST: IPv4, bridged vxlan4: PMTU exceptions                         [FAIL]

Let dd use directly the standard output to fix the above:
  # TEST: IPv4, bridged vxlan4: PMTU exceptions - nexthop objects       [ OK ]
