Allow vhost to be maybe opts['rhost']

This enables passing rhost and rport directly to send_request_cgi
without having to monkey with the datastore.

Fix Module.new bug and test for vhost
Update wol.rb to specify rhost/rport directly

 - [ ] Fire up tcpdump on the listening interface
 - [ ] Run the module and see the pcap:

Fix shodan to not muck with datastore
Include a vhost for Shodan or else it complains

Works now. The rhost option was not keeping the custom vhost option.

Replace RHOST reassing with just host

This looks okay from debug (the host looks like it's generating okay)
but there may be some subtle thing I'm not seeing here. @wchen-r7 can
you glance at this please?

[SeeRM #8498]
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.
