x86/prctl/uapi: Remove #ifdef for CHECKPOINT_RESTORE
As userspace knows nothing about kernel config, thus #ifdefs
around ABI prctl constants makes them invisible to userspace.
Let it be clean'n'simple: remove #ifdefs.
If kernel has CONFIG_CHECKPOINT_RESTORE disabled, sys_prctl()
will return -EINVAL for those prctls.
