fix builds on macOS Catalina (10.15.7)

The `_DARWIN_BETTER_REALPATH` flag fixes the file device reading directories.

The colors change fixes an integer size error in the code below it.

I have a few other quality of life commits on the `macbuild` branch of my
git.sr.ht/~apiarian/uxn fork for more Mac convenience, but the probably don't
belong in the main branch of uxn. Maybe we can explore adding them as build
flags?
