pam_cas and HTTP/1.1: a patch attached !

[Geoffroy DESVERNAY-3]

We've had some problems because of our apache proxy for cas service
being hosted as 'virtualhost': pam_cas couldn't validate any ticket with
HTTP/1.0 protocol.

Here is a little patch, adding a 'Host: ' header with the configured
hostname, and changing CAS_PROT to HTTP/1.1.

It works for us=E2=84=A2

Hope this can help ... more than without patch ;)
