Subject: libbpf: Remove BPF_EMBED_OBJ macro from libbpf.h
Patch-mainline: v5.6-rc1
Git-commit: 3bf3c79b772f4155312c000310abab700aba2200
References: bsc#1177028

Drop BPF_EMBED_OBJ and struct bpf_embed_data now that skeleton automatically
embeds contents of its source object file. While BPF_EMBED_OBJ is useful
independently of skeleton, we are currently don't have any use cases utilizing
it, so let's remove them until/if we need it.
