wc: Fix mapgen-related strings being in the wrong textdomain

The _ locals are there to ensure that if _ is overridden anywhere else
in the enclosing scope (which I haven't properly determined *where* it
is yet) it gets overridden again with the right textdomain object.
It *does* tell wmlxgettext what the correct textdomain is without using
the `-- #textdomain` hack anyway, so might as well just do it this way
regardless of the global-looking _ in map/main.lua.
