commit 71330842ff93ae67a066c1fa68d75672527312fa upstream.
Rename LOCKDOWN_BPF_READ into LOCKDOWN_BPF_READ_KERNEL so we have naming
more consistent with a LOCKDOWN_BPF_WRITE_USER option that we are
adding.
As far as I can tell, next bpf patch does not depend on this one and
we don't need it in 5.10. (Likely same situation with 5.13).
