lglicua-0.1-alpha4: Lua 5.4 support?

[sur-behoffski <sur_behoffski@...>]

G'day Roberto,

I've relied on Distribution Lua exe/dev packaging, and this has
impeded some progress on Lua version support.

Linux Mint and CentOS do not have Lua 5.4 packages.

Just now, some experiments with manual Lua installation shows that Ubuntu
20.04.2, 20.10 and 21.04 support Lua 5.4.

"lua5.4" and "liblua5.4-dev" need to be added manually
("sudo apt-get install"), but then all remaining Assistant steps, from
"./i lua-environment-force 5.4 fer-real" onwards, work cleanly.

More can be done to reduce reliance on OS-package support, but this is
non-trivial.

[There are historical reasons, stretching back to trying to get Gentoo
support in 2016, that shaped the current approach.]
