Subject: [PATCH] luaexpat: add Lua 5.4 variant

Add luaexpat5.4, parallel to existing luaexpat (Lua 5.1, default).
Builds against the Lua 5.4 headers under /usr/include/lua5.4 and
installs to /usr/lib/lua/5.4/. Same pattern as the luasocket 5.3
variant already shipped.

Needed for the prosody 13.x upgrade.
