Subject: [PATCH] tests/fetch-tests: avoid unnecessary copy-to-store

Previously path was concatenated using string interpolation. This commit
switches from string interpolation to path interpolation.

The problem is nix will copy the "${directory}" to a new store
object, meaning anything outside its root won't be available.

From the nix manual:

> A path in an interpolated expression is first copied into the Nix
> store, and the resulting string is the store path of the newly created
> store object.
