games-rpg/sumwars: migrate to lua-single.eclass

Set LUA_COMPAT to lua5-{1..2} because when left to its own devices,
upstream build scripts select 5.2 at most even when newer versions of
Lua are present in the system. Builds without errors also when
forced to use 5.3, then again the bunded data scripts may or may not be
compatible with that version so let's err on the side of caution.

This version of sumwars does not use the CEGUI Lua-scripting module
(CEGUILua is mentioned exactly once in the source code, in a
commented-out #include line) and does not link against the relevant
CEGUI library. Therefore, the value of LUA_SINGLE_TARGET used during the
building of dev-games/cegui can safely be disregarded.

Closes: https://bugs.gentoo.org/752702
