fault: Clean-up /usr/bin/env instances

The dependency resolver for RPM relies on the shebang to have the
interperter that will be used in order to get things right, so
change shebang to /usr/bin/python.

In other cases, the shebang is not needed at all as these are not
really executable python files, they are part of the python package.
RPMLINT finds these and complains that a non-executable has a shebang.
