Fix Lua type confusion bug

The only secure and robust way to check that a userdata is of the
expected type is to check its metatable.  Userdata metatables are not
changeable by Lua code without the debug library, so if the metatable is
a certain table, only C code could have made it so.  GLib type checking
functions are _not_ a robust or secure way to check that a block of
memory is a specific type of GObject, because Lua code could cause a
type confusion bug and potentially use it to forge pointers.

wplua: move under modules/module-lua-scripting

It's unlikely that wplua will ever be useful outside the context
of module-lua-scripting, so let's move it to keep all the code in one place
