Merge branch 'fix-libbpf-s-bpf_object-and-bpf-subskel-interoperability'

Andrii Nakryiko says:

====================
Fix libbpf's bpf_object and BPF subskel interoperability

Fix libbpf's global data map mmap()'ing logic to make BPF objects loaded
through generic bpf_object__load() API interoperable with BPF subskeleton
instantiated from such BPF object. The issue is in re-mmap()'ing of global
data maps after BPF object is loaded into kernel, which is currently done in
BPF skeleton-specific code, and should instead be done in generic and common
bpf_object_load() logic.

See patch #2 for the fix, patch #3 for the selftests.  Patch #1 is preliminary
fix for existing spin_lock selftests which currently works by accident.
