Makefile: make distclean target work

A mispelling in the Makefile in the root directory prevented "make
distclean" to go into subdirectories.

In libsemanage/src/, semanageswig_python_exception.i was not cleaned by
"make distclean" because the target did not use $(GENERATED) and this
variable was being redefined in the Makefile.

Fix these two bugs.
