[PATCH 1/5] selftests: net: fib_tests: skip rp_filter test if cls_basic is unavailable

The rp_filter test in fib_tests.sh installs tc filters using the
"basic" classifier but does not verify the corresponding kernel
module (cls_basic) is available. On kernels built without
CONFIG_NET_CLS_BASIC, the tc command fails and the rp_filter test
is reported as a failure.

Add a check for the presence of the cls_basic module and skip
the rp_filter test when the classifier is not available.
