Subject: [PATCH] Require sudo in .travis.yml

Since the install script currently requires sudo, we should state so
explicetely in the .travis.yml file to make sure we get a sudo-enabled
environment and not a container-based one, as there is no sudo available
in the latter one. The default was changed in August 2017, so when
forking this repository, the Travis CI won't work out-of-the box without
this modification. This is described in some details here [1].
