bugfix: Change to setup_logging so that it attempts to use the progra…

…m name

to determine log location instead of the __main__ module. This is because
sometimes the __main__ module is actually zprocess.process_class_wrapper,
for subprocesses started using the zprocess.Process class. To prevent their logs
ending up in the zprocess directory, we can use the name of the program to
determine the location of that program's __main__.py module instead.

This is particularly important on linux if you are not using
anaconda then zprocess may be installed somewhere without write permissions,
so the log file is not just misplaced but throws a permissions error.
