qapi: Fix array first used in a different module

We generally put implicitly defined types in whatever module triggered
their definition.  This is wrong for array types, as the included test
case demonstrates.  Let's have a closer look at it.

Type 'Status' is defined sub-sub-module.json.  Array type ['Status']
occurs in main module qapi-schema-test.json and in
include/sub-module.json.  The main module's use is first, so the array
type gets put into the main module.

The generated C headers define StatusList in qapi-types.h.  But
include/qapi-types-sub-module.h uses it without including
qapi-types.h.  Oops.

To fix that, put the array type into its element type's module.

Now StatusList gets generated into qapi-types-sub-module.h, which all
its users include.
