libperf tests: Add support for verbose printing
Add __T_VERBOSE() so tests can add verbose output. The verbose output is enabled with the '-v' command line option. Running 'make tests V=1' will enable the '-v' option when running the tests. It'll be used in the next patch, for a user space counter access test.
