btt: Added no remap option
Trying to run btt on pre-2.6.19 kernels has problems handling the
previous remap PDU - it did not include a proper device-from field.
(Probably should have bumped the blktrace version when we did that.)
This option just tosses those out as it just results in lots of crazy
stuff being handled.
