[dw-free] Make sure that crossposting between Dreamwidth/clones won't allow infinite loops

[afuna]

[commit: http://hg.dwscoalition.org/dw-free/rev/dd1198c129a5]

http://bugs.dwscoalition.org/show_bug.cgi?id=1484

Temporary fix to prevent crossposted entries from being crossposted back and
forth between two different DW-based sites in a never-ending loop. This
prevents crossposted entries from being crossposted again, entirely.

Patch by afuna.
