gnu: racket: fix raco exe with non-minimal Racket

This commit backports an upstream repair for a bug exposed by Guix's
change in Racket 8.2 to make the `racket` package a layered/tethered
installation that chains to the `racket-minimal` package. When using a
layered/tethered installation, the `setup/variant` library would fail to
recognize the default Racet variant (CS, 3M, or CGC), leading to
confusing failures from `raco exe`, `create-embedding-executable`, and
other clients.

For further details, see <https://issues.guix.gnu.org/50118> and
<https://github.com/racket/racket/issues/3969>.

* gnu/packages/patches/racket-minimal-backport-1629887.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/racket.scm (racket-minimal)[source]: Use it.
