[PATCH v4 06/12] tests/qtest/qos-test: dump environment variables if verbose

[Christian Schoenebeck <qemu_oss@crudebyte.com>]

If qtests are run in verbose mode (i.e. if --verbose CL argument
was provided) then print all environment variables to stdout
before running the individual tests.

Use qos_printf() instead of g_test_message() to avoid the latter
cluttering the output.
