Felix Uhl 1362a0a55a Fix logic for default XDG_DATA_DIRS value
The [POSIX test manpage](https://pubs.opengroup.org/onlinepubs/9699919799/utilities/test.html)
as well as the [fish test manpage](https://fishshell.com/docs/current/cmds/test.html#operators-for-text-strings)
specify that `-z` will be "True if the length of string string is zero;
otherwise, false."

The `-n` was likely a mixup and not caught during testing of
https://github.com/NixOS/nix/pull/8985 due to a lack of missing
conflicting entries in `XDG_DATA_DIRS`.
