[DEBUG] Make some debug output operators compile in factor.cpp...

...for the case when somebody actually #defines DEBUGFACTOR. The operators
must be in the same anonymous namespace in which umodpoly, upoly and upvec
are typedef'ed. (I'm not really sure I understand why but that's what GCC
and CLang are convinced of.)
