With the current Makefile, if the user tries something like make TARGETS="bpf mm"
only mm is run and bpf is skipped, which is not intentional. `bpf` and `sched_ext` are always filtered out even when TARGETS is set explicitly due to how SKIP_TARGETS is implemented. This default skip exists because these tests require newer LLVM/Clang versions that may not be available on all systems. Fix the SKIP_TARGETS logic so that bpf and sched_ext remain skipped when TARGETS is taken from the Makefile but are included when the user specifies them explicitly.
