Subject: [PATCH] gnu: luarocks: Add for Lua 5.2 and fix dependencies.

From: Timo Wilken <[email-masked]>
Date: Sun, 26 Feb 2023 17:08:19 +0100

Luarocks requires some external binaries, which should be set in its
config file instead of relying on the calling user's PATH containing
them.

Also, for use with Prosody, luarocks needs to be built against Lua
5.2, so provide multiple versions of the package, like for other Lua
packages.

* gnu/packages/lua.scm (make-luarocks): New function.
* gnu/packages/lua.scm (lua5.2-luarocks): New variable.
