docs: move protection-keys.rst to the core-api book

mchehab · Jonathan Corbet · commit 1eecbcdca2bd · 2019-06-08T13:42:12.000-06:00
This document is used by multiple architectures:

	$ echo $(git grep -l  pkey_mprotect arch|cut -d'/' -f 2|sort|uniq)
	alpha arm arm64 ia64 m68k microblaze mips parisc powerpc s390 sh sparc x86 xtensa

So, let's move it to the core book and adjust the links to it
accordingly.
