Subject: Add missing LUA_BUILD_AS_DLL definition to the liblua target.

Fixes lua.dll being generated without public symbols by the Visual Studio compiler;
- when building a DLL you either need a DEF file listing the public symbols or use __declspec(export) in the public symbols.
- when linking to a DLL you only need to use __declspec(import) when referencing data,
  since lua only exports functions it isn't needed for the other targets.
