tests: Hide INFO and DEBUG messages by default

Tracker's DEBUG and INFO messages are very verbose -- thousands of lines
each time you open a TrackerSparqlConnection, which some tests do many
times. Let's hide the output by default, guarded behind the
TRACKER_TESTS_VERBOSE environment variable which the functional-tests
are already using.

The size of the meson-logs.txt file reduces from 27MB to about 100KB
with this change.

Any really useful debug messages which are being lost after this change
could be promoted to g_message() to ensure they are always logged.
