python-utils-r1.eclass: Enable parallel bytecompile compilation

Browse Source 
Python 3.5 added support for compileall to run parallel workers for
performing bytecode compilation. Make use of it to the extent
possible without refactoring the code too much to get different
paths into the same call for best possible parallelization.
