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.
