Send only the path and not the full URI to httplib.request

Sending the full uri was causing httplib to send requests as:

POST http://ipa.example.com/ca/admin/ca/getStatus HTTP/1.1

From what I can tell tomcat changed its URL handling due to a CVE
(BZ 1552375). This has been wrong in freeipa since the CA status
checking was added, d6fbbd5 , but tomcat handled it fine so we
didn't notice.
