vnc: avoid underflow when accessing user-provided address
If hostlen is zero, there is a possibility that addrstr[hostlen - 1]
underflows and, if a closing bracked is there, hostlen - 2 is passed
to g_strndup() on the next line. If websocket==false then
addrstr[0] would be a colon, but if websocket==true this could in
principle happen.
Fix it by checking hostlen.
