bpf: Move bpf map owner out of common struct

Upstream commit: fd1c98f0ef5cbcec842209776505d9e70d8fcd53

Given this is only relevant for BPF tail call maps, it is adding up space
and penalizing other map types. We also need to extend this with further
objects to track / compare to. Therefore, lets move this out into a separate
structure and dynamically allocate it only for BPF tail call maps.
