Most integration tests depend on the $HOSTALIASES environment variable being functional. That variable works on most systems, but not all. In particular, systems with `systemd-resolved` can cause the variable to be ignored. This was reported by Alex Ellwein in https://github.com/albertito/chasquid/issues/20. This patch makes the affected tests to be skipped if $HOSTALIASES is not working properly. It also removes unnecessary hosts files from tests which don't need it, and documents this behaviour. Thanks to Alex Ellwein and foxcpp@ for reporting and helping investigate this issue!
