[bug#74723] [PATCH 02/19] gnu: carla: Fix making carla executable.

[Sughosha]

This commit fixes lmms opening carla.

* gnu/packages/audio.scm (carla)[arguments]<#:phases>: In make-carla-executable
phase, also make carla-control, carla-jack-multi, carla-jack-single,
carla-patchbay and carla-rack executable. In wrap-executables phase, also wrap
the other executables and resources.
