[PATCH] libbpf: Update the comment to remove the reference to the deprecated interface bpf_program__load().

[Jianyun Gao]

Commit be2f2d1680df(Deprecate bpf_program__load() API) marked
bpf_program__load() as deprecated starting with libbpf v0.6. And later
in commit 146bf811f5ac(remove most other deprecated high-level APIs)
actually removed the bpf_program__load() implementation and related old
high-level APIs.

This patch update the comment in bpf_program__set_attach_target() to
remove the reference to the deprecated interface bpf_program__load().
