bpf, verifier: avoid retpoline for map push/pop/peek operation

Browse source

Extend prior work from 09772d92cd ("bpf: avoid retpoline for
lookup/update/delete calls on maps") to also apply to the recently
added map helpers that perform push/pop/peek operations so that
the indirect call can be avoided.
