Subject: libbpf: Rename bpf_prog_attach_xattr() to bpf_prog_attach_opts()
Patch-mainline: v5.18-rc1
Git-commit: d6c9c24e891216890264320f5534051fd196ace8
References: jsc#PED-1377

All xattr APIs are being dropped, let's converge to the convention used in
high-level APIs and rename bpf_prog_attach_xattr to bpf_prog_attach_opts.
