Subject: [PATCH 2/3] Set linux distro (xenial) as global config

All jobs require (at least) xenial anyway, so it is about time to move
it to a global config.

Subject: [PATCH 3/3] Stop running cppcheck on osx

The homebrew install takes unreasonably long and effectively breaks
travis. While it would be great to run cppcheck on all systems, the cost
isn't worth it on travis infrastructure.

The implementation is slightly more precise than a host check - it
checks if a cppcheck program is available.
