[PATCH net-next v2] selftests/net: call sendmmsg via udpgso_bench.sh

[Kenjiro Nakayama]

Currently, sendmmsg is implemented in udpgso_bench_tx.c,
but it is not called by any test script.

This patch adds a test for sendmmsg in udpgso_bench.sh.
This allows for basic API testing and benchmarking
comparisons with GSO.
