Added '-verbose' option to ant command

Added the '-verbose' option to ant command to get more context
in case of any error which helps in debugging

Test: Run code coverage report generation for
support_lib(atp/test_runs/4672827) with the verbose option in ant
command and you could find a more detailed error than the one in the logs
