ut/reduce: add ut_build_data_buffer function 



This function can be used to create data buffers
with varying levels of compression - we'll use
this in upcoming patches to test how lib/reduce
actually handles compressed buffers.

Modify the unit tests for the compression algorithm
to use this new function as well.
