Thank you for review.

I've fixed it, so that luarocks should install rocks into
/usr/share/lua/luarocks, and updated packages [1].

* lua53, lua53-luarocks,
* lua54, lua54-luarocks.

And, here is a sample script to see whether luarocks works or not:

--------
luarocks-5.4 install argparse \
&& luarocks-5.4 list \
&& lua5.4 -e 'require("argparse")' && echo OK \
&& luarocks-5.4 remove argparse

luarocks-5.3 install argparse \
&& luarocks-5.3 list \
&& lua5.3 -e 'require("argparse")' && echo OK \
&& luarocks-5.3 remove argparse
--------
