qapi: Share test_init code in test-qmp-input*

Rather than duplicate the body of two functions just to
decide between qobject_from_jsonv() and qobject_from_json(),
exploit the fact that qobject_from_jsonv() intentionally
takes 'va_list *' instead of the more common 'va_list', and
that qobject_from_json() just calls qobject_from_jsonv(,NULL).
For each file, our two existing init functions then become
thin wrappers around a new internal function, and future
updates to initialization don't have to be duplicated.
