linux-yocto/5.4: temporarily revert IKHEADERS in standard kernels
We had a commit that enabled IKHEADERS, since bpf requires them on
target.
This is still causing incremental reproducibility errors during the
module compilation phase of the build.
We are temporarily turning this off, so we can integrate -stable
and other related changes. A replacement feature "reproducibility"
is also being added to this can be conditionally enabled while
we debug.
