[bug#42682] [PATCH 2/2] gnu: Add qmk-cli.

Turns out qmk_cli is just a wrapper around qmk_firmware. It clones qmk
firmware repository because it cannot locate a qmk_firmware directory
using QMK_HOME variable.

I think the proper way to do things would be to package qmk_firwmare
first (it has a root shell.nix file that should help). Then this package
would define QMK_HOME using "search-paths".

This way, qmk_cli would just require some python libraries, but would
not propagate git, and the toolchains.

Does it make sense?

Thanks,

Mathieu
