Merge branch 'Improve set_attach_target() and deprecate open_opts.attach_prog_fd'

Andrii Nakryiko says:

====================

This patch set deprecates bpf_object_open_opts.attach_prog_fd (in libbpf 0.7+)
by extending bpf_program__set_attach_target() to support some more flexible
scenarios. Existing fexit_bpf2bpf selftest is updated accordingly to not use
deprecated APIs.

While at it, also deprecate no-op relaxed_core_relocs option (they are always
"relaxed").

Last patch also const-ifies all high-level libbpf attach APIs, as there is no
reason for them to assume bpf_program/bpf_map modifications.

Patch #1 also removes one more unneeded use of find_sec_def(), relying on
prog->sec_def that's set during bpf_object__open() operation, simplifying
upcoming refactoring a little bit more.

All these changes are preparatory patches before SEC() handling refactoring
that will come next.
