tests: Fix static-link test when running installed

This effectively reverts commit 663ee11fda
for this `meson.build` file. This `meson.build` file isn’t actually
pulled into the main GLib (or GIO) build; it’s actually just installed
and then later called from a `meson` subprocess of `static-link.py`.

So it doesn’t have access to the `app_profile_dep` variable, which is
internal to GLib.

Fixes this CI failure: https://gitlab.gnome.org/GNOME/glib/-/jobs/5834610
