perf test: Keep test result clean if '-v' not set
According to [1], 'perf test' should avoid output too much information
if '-v' is not set, only 'Ok', 'FAIL' or 'Skip' need to be printed.
This patch removes several messages sent directly to stderr to make
the output clean.
Before this patch:
# perf test dummy
23: Test using a dummy software event to keep tracking : (not supported) Ok
After this patch:
# perf test dummy
23: Test using a dummy software event to keep tracking : Skip
