[bug#55999] [PATCH v2 1/2] gnu: packages: Replace rdmd with d-tools.

[(]

* gnu/packages/dlang.scm (rdmd): Remove variable.
* gnu/packages/dlang.scm (d-tools): New variable.

This fixes the build of rdmd and updates it to the latest version, along
with running rdmd_test.d, building dustmite along with rdmd, and
renaming the package to d-tools to reflect that change.

-minimize the amount of work necessary.  Unlike make, rdmd tracks dependencies
-and freshness without requiring additional information from the user.")
