gnu: the-powder-toy: Enable building on more architectures.

* gnu/packages/games.scm (the-powder-toy)[source]: Add a snippet to
identify more machines as 64-bit.
[arguments]: Add configure-flags when building with lua.  Add a phase to
correctly use lua when necessary.
[inputs]: Build with luajit or lua-5.2 depending on platform support.
