travisはFedoraのDocker imageを使用するようになる

PRのコメント: ueno/libkkc@e5adcf4
を参考にして必要の無さそうなパッケージを削って作成しました
この状態ではcoverallsがレポジトリを見つけられないため、オーナーによって
```
gem install travis
cd /srcdir
travis encrypt COVERALLS_REPO_TOKEN="coveralls.io libskk_repo_token" --add
```
する必要があると思っています

私はBUILD_OPTS環境変数の意味を殆ど理解していないためこの部分を触っていません
