[Toybox] macOS realpath test failures

[Rob Landley]

I note I'm building mkroot images for the release so this bugfix won't be in
0.8.9, but Android has its own sync points. :)

This has been on my todo list because I need to make an f2fs filesystem, which
is flash based, so I need to fake up a flash device with an erase block size. (I
did that years ago and need to find my notes. Possibly easiest to do with qemu
instead of that weird annotate-a-block-device driver?)

The -s says "don't expand symlinks" so logically it means ".." should strip the
last entry off of $PWD instead of traversing the filesystem? (That's why it
expects that output, anyway...)

The ls contents look right. I'll see if I can set up a test environment later
today...
