blktrace: fix timestamp in binary output

I found the timestamp is wrong:

 # echo bin > trace_option
 # echo blk > current_tracer
 # cat trace_pipe | blkparse -i -
 8,0    0        0     0.000000000   504  A   W ...
 ...
 8,7    1        0     0.008534097     0  C   R ...
            (should be 8.534097xxx)

user-space blkparse expects the timestamp to be nanosecond.
