THRIFT-929. cpp: Reduce default buffer sizes for TransportTest

Reduce the default test buffer sizes by about 30x, reducing the time it
takes to run TransportTest from about 1 minute to about 2 seconds.  I
added a --size-multiplier argument that can be used to adjust the sizes
of all test buffers, so developers can still run with large buffer sizes
when desired.
