Commit Message

Andrii Nakryiko Jan. 2, 2024, 7 p.m. UTC 
With all the preparations in previous patches done we are ready to
postpone BTF loading and sanitization step until after all the
relocations are performed.

While at it, simplify step name from bpf_object_sanitize_and_load_btf
to bpf_object_load_btf. Map creation and program loading steps also
perform sanitization, but they don't explicitly reflect it in overly
verbose function name. So keep naming and approch consistent here.
