Tools: Testbench: Set trace level to info when option quiet is set

The default testbench trace level debug consumes a lot of
processing time due to large amount of prints. It also adds
a lot to measured MCPS with xtensa build of testbench.

As fix the command line option -q is set to control
host_trace_level. In quiet mode the level is set to info. It
is a suitable level for code profiling and performance
measurement.
