Refuse to proceed if no HOST[:PORT] is provided after the options.

Browse Source 
Prior to this patch, if the user fails to provide a host:port after
specifying cipherscan options, the script runs sed on an empty variable
(failing with a syntax error) and then asttempts to cipherscan the
target ':443'.

This adds a simple test to ensure that a target was actually provided.
