manager: enable fuzzer verbosity only if -debug flag is given

Browse Source 
It is not useful to pass manager verbosity flag to fuzzer,
as fuzzer output is not visible. But it increases amount of fuzzer
output that needs to be parsed by manager. Also increased fuzzer
verbosity reduces effective crash log size (less programs fit).
Enable fuzzer verbosity only if debug flag is given.
