We need a separate tsflag to control bpf extension feature so that
we will not affect the behaviors of existing applications.

The idea of introducing requestors for better extension (not only
serving bpf extension) comes from Vadim Fedorenko.

As also said in the cover letter: I prefer sk_tstflags_bpf.

This array approach adds code churn, may have cacheline effects by
moving other fields and anticipates I don't see a third requestor
happening. And if it does, we'll deal with it then.

Got it. Thanks. I will adjust it accordingly.
