Subject: bpf: add bpf_patch_insn_single helper

From: Daniel Borkmann <[email protected]>

commit c237ee5eb33bf19fe0591c04ff8db19da7323a83 upstream.

Move the functionality to patch instructions out of the verifier code and into the core as the new bpf_patch_insn_single() helper will be needed later on for blinding as well. No changes in functionality.
