Subject: [PATCH 2/6] selftests: forwarding: sch_ets: skip test if cls_basic module is missing

The sch_ets.sh test requires the cls_basic kernel module to function
properly. If the kernel is compiled without CONFIG_NET_CLS_BASIC,
the test fails instead of being gracefully skipped.

Add a check to attempt loading the cls_basic module. If modprobe fails,
the test will be skipped.
