rtla/tests: Run Test::Harness in verbose mode

Add -v flag to prove command to also print the names of tests that
succeeded, not only those that failed, to allow easier debugging of the
test suite.

Also, drop printing the option and value to stdout in
check_with_osnoise_options, which was a debugging print that was
accidentally left in the final commit, and which would be otherwise now
visible in make check output, as stdout is no longer suppressed.
