tools lib traceevent: Remove extra '\n' in print_event_time()

If the precision of print_event_time() is zero or greater than the
timestamp, it uses a different format. But that format had an extra new
line at the end, and caused the output to not look right:

cpus=2
           sleep-3946  [001]111264306005
: function:             inotify_inode_queue_event
           sleep-3946  [001]111264307158
: function:             __fsnotify_parent
           sleep-3946  [001]111264307637
: function:             inotify_dentry_parent_queue_event
           sleep-3946  [001]111264307989
: function:             fsnotify
           sleep-3946  [001]111264308401
: function:             audit_syscall_exit
