Lua 5.1 is EOL and many downstream packages need 5.2+. Mirror the
luasocket multi-variant pattern: keep luafilesystem (Lua 5.1, default)
and add luafilesystem5.4 which builds the same source against
liblua5.4 and installs to /usr/lib/lua/5.4/.
Needed for the prosody 13.x upgrade (Lua 5.1 unsupported upstream).

There are roughly 50 Lua packages.
It's about time we consider a proposal for moving all of them
under a lang/lua sub-folder.
