[Toybox] Valid range for stat userID and groupID?

[enh]

are you building with bionic? glibc won't know what android does with
uid/gid for apps. (also, 4294967295 is -1.)

i couldn't find any files on a Pixel XL where the built-in toybox
reported unusual uids or gids.

as usual, not using Android's libc on an Android device is likely to
lead to confusing results.
