[web-nfc] Security section (#264)

kenchris has just created a new issue for https://github.com/w3c/web-nfc:

== Security section ==
When I copied the security section content to the wake lock spec, I was told that we cannot write it that way so need to dig up the old discussion and fix it here as well
