Todd Gamblin 5aa05b8ef4 travis: require sudo in an attempt to avoid build timeouts (#9327) ... - Many container builds are timing out frequently during Spack tests in Travis CI. - Travis recommends to try `sudo: required` to see whether this is an infrastructure issue or something else. - added `sudo: required` to all Linux builds. - added --verbose to `spack test` invocation so that we can see more easily what tests it's timing out on.
