x86: Enable -fcf-protection with multi-byte NOPs
-fcf-protection no longer depens on -mcet and with revision 259522:
commit d59cfa9a4064339cf2bd2da828c4c133f13e57f0
Author: hjl <hjl@138bc75d-0d04-0410-961f-82ee72b054a4>

Define __CET__ for -fcf-protection and remove -mibt
-mcet becomes an alias for -mshstk. Since all usages of -mcet and
-mno-cet have either been removed or replaced, we can remove the -mcet
command-lint option.
