[Toybox] [PATCH] Fix dev_minor()/dev_major()/dev_makedev() for Mac.

[enh]

Major/minor device encoding is not portable. No two BSDs agree with
each other, and Darwin is different again.

Everyone does agree on having major()/minor()/makedev() macros, but
they disagree whether they should be in <sys/types.h> (the BSDs
including Darwin, and old versions of glibc) or <sys/sysmacros.h>
(glibc >= 2.26 and bionic).

This fixes `ls -l /dev/zero` and `stat /dev/zero` on Mac.
