[Toybox] reason for realpath in df?

[enh]

one of the obvious remaining differences between toybox df and
coreutils (or Android) df is that it follows symbolic links in the
first column. the git history doesn't explain why this change was
made, though it was clearly deliberate. can you remember why?

    Follow symlinks to get actual device name, getmountlist() reverses
order for us now, detect stdout to full device.

...

+       device = *mt->device == '/' ? realpath(mt->device, NULL) : NULL;
+       if (!device) device = mt->device;
