On macOS in the `nix develop` shell, `make
tests/functional/logging.sh.test` errors:

error: path '/var' is a symlink

This is because `mktemp` returns a path like
`/var/folders/z5/fclwwdms3r1gq4k4p3pkvvc00000gn/T/tmp.qDY24l6bIM`,
where `/var` is a symlink to `/private/var`.
Then, we attempt to use that path as a `builder`, which errors because
symlinks are impure or whatever.
Anyways, we can fix this by using `realpath "$(mktemp)"` instead of
`mktemp` directly.
NB: This error doesn't seem to happen when I run the tests through `nix
flake check`. I'm not sure if Nix does something to `TMP` in that case.
