Fix rockspec modules

[Aire-One]

Hello 👋

After installing the rock with the command from the wiki https://github.com/lcpz/lain/wiki

luarocks install lcpz/lain

The installation works successfully, but the installed package is broken.

/home/aireone/.luarocks/share/lua/5.4/lain/init.lua:12: module 'lain.layout' not found points to https://github.com/lcpz/lain/blob/master/init.lua#L12

And ls in this directory only outputs the init.lua file (as expected)

$ ls /home/aireone/.luarocks/share/lua/5.4/lain/
init.lua

According to https://github.com/luarocks/luarocks/wiki/Creating-a-rock#building-a-module, the modules = { lain = "init.lua" } configuration tells Luarocks to install only the init.lua file.

This PR fix the modules list and make the rockspec file install all the modules (expect util/dkjson.lua which is installed by the required dependencies).

It can be tested locally with the installation command (Note to anyone wanting to test that without cloning the repo: you can also use an HTTP URL to the file on GitHub):

luarocks --local install lain-scm-1.rockspec

After that, the rock can be loaded successfully from an Awesome WM config.

Here is the output luarocks show lain gives me. As expected, there is now the full list of modules installed.

$ luarocks show lain

lain scm-1 - Layout, widgets and utilities for Awesome WM

Alternative layouts, asynchronous widgets and utility functions for Awesome WM.
Non-Lua dependency: curl (for IMAP, MPD and weather widgets).

Are the commas at lines 5, 11, 15, 53 and 54 necessary?

[Aire-One]

No, they aren't. I have added them out of habit (or rather, my formatter put them and I kept them).

I have force-pushed to remove them.
