New policy for pyzor

[David Hampton]

This is a new strict policy for the pyzor spam filter.  It is based on
the selinux-policy-strict-sources-1.23.2-1 fedora RPM.  This policy
requires the definition of a pyzor reserved port that was in the
net_contexts diff I sent last Wednesday.  Please let me know if there
are any problems with or changes needed to this policy.
