Revert "selinux: Relocate ss_initialized and selinux_enforcing to separate 4k"

This reverts commit d4807bd60d.

That out of tree patch causes the resulting kernel image to be too
large, causing ld.lld to error; likely due to the additional section and
alignment requirements.  Android and floral don't host virtual targets
and thus do not run at EL2 on arm64.
