setjmp.h: add the missing __returns_twice to sigsetjmp().

setjmp() and _setjmp() were already correct, but we'd missed
sigsetjmp(). Found while investigating a toybox timeout(1) failure on
macOS, which doesn't annotate _any_ of these functions.

Also add all the missing doc comments while I'm here.
