tools lib traceevent: Have bprintk output the same as the kernel does

The trace_bprintk() in the kernel looks like:

 ring_buffer_producer_thread: Missed:   0
 ring_buffer_producer_thread: Hit:      62174350
 ring_buffer_producer_thread: Entries per millisec: 6296
 ring_buffer_producer_thread: 158 ns per entry
 ring_buffer_producer_thread: Sleeping for 10 secs
 ring_buffer_producer_thread: Starting ring buffer hammer
 ring_buffer_producer_thread: End ring buffer hammer

But the current output looks like this:

 ring_buffer_producer_thread : Time:     9407018 (usecs)
 ring_buffer_producer_thread : Overruns: 43285485
 ring_buffer_producer_thread : Read:     4405365  (by events)
 ring_buffer_producer_thread : Entries:  0
 ring_buffer_producer_thread : Total:    47690850
 ring_buffer_producer_thread : Missed:   0
 ring_buffer_producer_thread : Hit:      47690850

Remove the space between the function and the colon.
