Description of problem:
The update of jsch broke backwards compatiblity with maven-wagon causing it to
be unbuildable. This change was caused by jsch breaking one method into two
separate methods. Instead of just patching maven-wagon to get around this, I am
submitting a patch for the jsch package instead in hope it might help others
with the same problem.

Version-Release number of selected component (if applicable):
0.1.31

Steps to Reproduce:;;;
try and build the maven-wagon package from rawhide, it will fail due to
KnownHosts.add having it method signature changed.

Additional info:
The supplied patch will fix this issue
