selftests: net: don't access /dev/stdout in pmtu.sh
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 ]
Fixes: 136a1b434bbb ("selftests: net: test vxlan pmtu exceptions with tcp")
