package/efl: depend on LuaJIT

Luajit is a provider for luainterpreter. We can't select providers of
virtual packages; we can only depend on them.

Note also that it is not very clear whether the host and target variants
of EFL need to be built with the same lua interpreter. Today, this is
guaranteed as we inly use luajit in both cases. But there were issues
with lua 5.1 in the past, so stick to only using luajit.

  - depend on luajit, not "any" luainterpreter
  - which keeps the host and target variants built with the same
    interpreter
