selftests/bpf: Add kfunc set test to resolve_btfids

Browse source

Extend the resolve_btfids selftest to cover kfunc sets defined with
BTF_KFUNCS_START/BTF_KFUNCS_END.

The test verifies that resolve_btfids correctly processes BTF_ID_FLAGS,
resolves function IDs, and checks the kfunc set is sorted.
