Make gnome-shell-extension-prefs a binary executable

Since commit 1ebb162a00 moved JS sources into resources,
the extension-prefs tool was broken. To fix it, we would either
need to generate an external GResource in addition to the generated
C code and teach gjs-console about loading it before evaluating
the script, or turn gnome-shell-extension-prefs into a binary with
the JS resources compiled in.
