[travis] Add minimal .travis.yml file
Allow for automated builds via Travis CI (https://travis-ci.org).
Note that the bin-i386-linux build platform is deliberately omitted
since the required linux-libc-dev:i386 package is not on the allowed
packages list for the Travis 14.04 ("trusty") container environment.
