bpf: Wrap aux data inside bpf_sanitize_info container

commit 3d0220f6861d713213b015b582e9f21e5b28d2e0 upstream.

Add a container structure struct bpf_sanitize_info which holds
the current aux info, and update call-sites to sanitize_ptr_alu()
to pass it in. This is needed for passing in additional state
later on.
