qemu: fix well-formed migration URI formatting

Browse Source 
When adding an automatically allocated port to a well-formed migration
URI, keep it well-formed:

  tcp://1.2.3.4/  ->  tcp://1.2.3.4/:12345   # wrong
  tcp://1.2.3.4/  ->  tcp://1.2.3.4:12345/   # fixed
  tcp://1.2.3.4   ->  tcp://1.2.3.4:12345    # still works
  tcp:1.2.3.4     ->  tcp:1.2.3.4:12345      # still works (old syntax)
