gnu: racket: Use Git origins for Racket packages.

* gnu/packages/patches/racket-gui-tethered-launcher-backport.patch:
Adjust path.
* gnu/packages/racket.scm (racket-packages-origin)
(simple-racket-origin): New procedures.
(extend-layer): Rename to ...
(configure-layer.rkt): ... this variable.  Tweak command-line arguments.
Adapt to 'config-tethered-apps-dir'.
(racket): Stop inheriting from 'racket-minimal'.
[version]: Use '%racket-version'.
[source]: Stop using bundled tarball.
[inputs]: Remove labels. Add 'racket-minimal' and package sources.
[native-inputs]: Reduce to racket-minimal.
Untested, as cross-compilation doesn't work yet.
[arguments]: Rewrite to use G-expressions, package sources from
'inputs', an explicit 'install' phase, and the revised
'configure-layer.rkt'.
