[WIP][.travis.yml] use travis in all tests instead of jenkins.

related to #973 (comment).

we cannot use travis directly on kinetic, please consider to use USE_DOCKER=true. (refer: https://github.com/jsk-ros-pkg/jsk_travis/blob/master/.travis.yml#L51)
And I think it is simpler that declare USE_DOCKER=true globally for testing of all distros.

As far as I see what you are discussing on #973 (comment), when testing on docker on travis, we need to configure each environment variables to pass to docker ( https://github.com/jsk-ros-pkg/jsk_travis/blob/master/travis.sh#L78-L91 ) like jenkins unfortunately.

travisの結果のメモ

hydroはtravisだと失敗．

indigoでは環境変数IS_EUSLISP_TRAVIS_TESTがわたってroseusのテストが走る．

[hrpsys_ros_bridge:cmake] Execute rostest for euslisp unittest

jenkinsだとダメでtravisだとOKなので，#973 (comment) で合っていた．
ただ，50分で終わらない．

@mmurooka
こちらについてですが、#1085 において、IS_EUSLISP_TRAVIS_TESTをjenkinsに渡すことで、euslispのテストがjenkinsでも走るようにしました。
もしこれで大丈夫でしたら、こちらのcloseをお願いします。
