bpf: add bpf_clone_redirect to bpf_helper_changes_pkt_data

The bpf_clone_redirect() still needs to be listed in
bpf_helper_changes_pkt_data() since we call into
bpf_try_make_head_writable() from there, thus we need
to invalidate prior pkt regs as well.

Fixes: 36bbef52 ("bpf: direct packet write and access for helpers for clsact progs")
