bitbake: fetch2: BB_ALLOWED_NETWORKS should not care about port numbers

Bitbake would fail to classify the following URL as belonging to a
allowed network, because of the port number in the url.

 BB_ALLOWED_NETWORKS = "*.example.com"
 SRC_URI = "http://git.example.com:8080/foo.tar.gz"

Since protocols aren't specified in the BB_ALLOWED_NETWORKS variable,
it's reasonable to believe that this should work regardless of protocol
being used.
