[PULL 17/17] tests/qtest: Don't print messages from query instances

[Juan Quintela <quintela@xxxxxxxxxx>]

From: Fabiano Rosas <farosas@xxxxxxx>

Now that we can query more than one binary, the "starting QEMU..."
message can get a little noisy. Mute those messages unless we're
running with --verbose.

Only affects qtest_init() calls from within libqtest. The tests
continue to output as usual.
