gnu: racket: Don't inject store paths into Racket files.

Apparently, during grafting, Guix can somehow mangle compiled
Racket CS files (.zo) such that Racket will refuse to load them.
(Maybe it has something to do with compression?)
So, we stop patching Racket sources with absolute paths to store
files (i.e. for foreign libraries to dlopen).
Instead, we put them in a data file that doesn't get compiled or,
in one case, embed it in C.

Fixes https://issues.guix.gnu.org/47064

* gnu/packages/patches/racket-sh-via-rktio.patch: New file.
Adds a special case at the C level, controlled by a preprocessor macro,
to handle attempts to execute "/bin/sh".
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/scheme.scm (racket)[source](patches): Apply it.
(racket)[arguments](#:configure-flags): Add the CPP flag to enable it.
(racket)[arguments](#:modules): Use srfi-1.
(racket)[arguments](#:phases): Remove 'patch-/bin/sh and 'pre-configure.
Change 'pre-configure-minimal to just change directory.
Add 'patch-config.rktd-lib-search-dirs after 'build and before 'install
to configure Racket's "lib-search-dirs".
(racket, racket-minimal)[inputs]: Add bash-minimal as an explicit input.
(racket-minimal)[source]: Adjust to inherit patches from racket.
(racket-minimal)[arguments]: Inherit from racket: changes no longer needed.
