binary_module_SUITE: Remove unnecessary calls to the binref module
The compile_pattern/1 function in the binref module is a dummy function. Therefore, calling binref:match/2 once with the plain pattern and once with a "pre-compiled" pattern will take twice as long, but will not help us find more errors. I shaved off one fourth of the running time for random_ref_comp/1 by eliminating the unnecessary calls to the binref module.
