Do the absolute minimal amount of modifications to eradicate
Py_FatalError() from module initialization functions.  The importing
mechanism already checks for PyErr_Occurred() after module importation
and it Does The Right Thing.

Unfortunately, the following either were not compiled or tested by the
regression suite, due to issues with my development platform:

	almodule.c
	cdmodule.c
	mpzmodule.c
	puremodule.c
	timingmodule.c
