libqtest: Introduce qtest_qmpv() and convert remaining macro

In order to convert qmp() macro to an inline function, expose a
qtest_qmpv() function, reused by qtest_qmp().

We can't apply GCC_FMT_ATTR() since fdc-test is using zero-length format
strings, which would result in warnings treated as errors.
