Use the current sezpoz version in the Eclipse files

We recently upgraded sezpoz to a new version (1.9-imagej) so sezpoz-1.9
is no longer downloaded by Maven. Therefore, we need to adjust all the
.factorypath files.

This commit was performed by:

perl -pi -e 's/1.9\/sezpoz-1.9/1.9-imagej\/sezpoz-1.9-imagej/' \
$(git grep -l sezpoz-1.9)
