games-strategy/openra: migrate to lua-single.eclass

Very much lua5.1-specific because the relevant library name to look for
is hard-coded into Eluant.

The environment should also be ready in the event someone decides to run
the make target check-scripts as (part of) tests - the wrapper created
by Lua eclasses will automatically have 'luac' point to 'luac5.1' so all
enabling this should require is adding the right version of dev-lang/lua
to BDEPEND.
