    Improve Travis test coverage and simplify config
    
    Specify the xenial (16.04) image, as Travis still sometimes uses 14.04
    by default.  Use cmocka from the package repository instead of
    building it.  Remove python3-paste as paste is no longer a test
    dependency, but add python3-kdcproxy.  Install pyrad via pip3 as the
    Ubuntu-packaged version still has the assertion bug.
