Make the -qtest-log be conditional on the --verbose flag, along with
the existing QTEST_LOG to avoid noisy qtest_memread() messages. Those
are particularly annoying for migration-test because all tests read
guest memory at the end and the QMP messages get lost in a flood of:

[R +1.096069] read 0x63ce000 0x1
[S +1.096071] OK 0xb8
[R +1.096077] read 0x63cf000 0x1
[S +1.096079] OK 0xb8
...
