gnu: Use self-references to inputs for #:disallowed-references.

This allows ‘package-input-rewriting’ to operate as expected on these
packages.  Failing that, rewritten packages would still carry references to
non-rewritten packages in #:disallowed-references.

* gnu/packages/admin.scm (wpa-supplicant-gui): Use ‘this-package-native-input’
for #:disallowed-references.
* gnu/packages/fontutils.scm (freetype): Likewise.
* gnu/packages/glib.scm (glib-minimal): Likewise.
