package/luajit: depend on !BR2_PACKAGE_LUA

We can't enable lua and luajit at the same time as they both provide
the virtual luainterpreter package.

Fixes:
package/luajit/luajit.mk:80: *** Configuration error: both "luajit" and "lua" are selected as providers for virtual package "luainterpreter". Only one provider can be selected at a time. Please fix your configuration.  Stop.
