sandbox: move away from separate macossandbox

Dropped prefixsandbox feature (protected at path level of $EPREFIX), to
align with master branch more.
Made macossandbox and macosusersandbox an execution mode of sandbox on
OSX platforms.
Documented that OS X sandbox is used, but that it is awfully slow (hence
sandbox is still not enabled by default for OSX (in Prefix)).

 .B sandbox
 Enable sandbox\-ing when running \fBemerge\fR(1) and \fBebuild\fR(1).
+On Mac OS X platforms that have /usr/bin/sandbox-exec available (10.5
+and later), this particular sandbox implementation is used instead of
+sys-apps/sandbox.  Note that using Mac OS X sandbox slows down the
+emerge process considerably, in particular for write operations.

 .B sesandbox
 Enable SELinux sandbox\-ing.  Do not toggle this \fBFEATURE\fR yourself.
