[Toybox] [PATCH] macOS: move struct sysinfo out of GLOBALS.

[Rob Landley]

Even if we don't build ps, we can't have a Linux-only struct in GLOBALS.
The obvious alternative to this would be to have a fake struct sysinfo
in lib/portability.h. Since having a real macOS replacement for
sysinfo(2) seems unlikely at this point, I went this route instead.

I need to add a comment in that list where we stop populating that from
/proc/$PID/stat and start just adding new fields to the end. (You inserted and
moved stuff and I went "um...".)

Just looked it up, and the last one from stat is SLOT_endbss. So this is all
after that and can move freely. Ok then.
