/area libpman

Does this PR require a change in the driver versions?

What this PR does / why we need it:

Allow to specify multiple program names for each event type and try to inject each of them until success.
This allows us to inject bpf_loop sendmmsg and recvmmsg programs where supported, and fallback at a program just sending first message where it isn't.
