Two more java payloads that wanted to write RHOST

There are three total, and they're all copy-pasted from the original
module from 2009. I suspect this idiom isn't used at all any more -- I
can't detect a difference in the payload if I just declare a host being
cli.peerhost, rather than rewriting RHOST to be cli.peerhost.
