Removed the unused testing for the __builtin__ module.

The previous commit in this branch fixed the text "__builtins__", however the __builtin__ is no
longer imported by any part of relax and hence the test is unneccessary.

Rathar than placing the 'C_module_exp_fn' variable into __builtin__ from the specific_fns.relax_fit
module, it is now placed into the global namespace of that module. The generic_fns.runs module then
simply imports the variable.

Removed the unneccessary usage of __builtin__.

The following varibles have been shifted from __builtin__ to the global namespace of the 'io' module

bz2_module_message
devnull_import
devnull_import_message
