Yohei Yukawa 3d4e01e667 Use Trusty environment on Travis CI ...

The 3GB memory limit enforced to Travis CI container-based environment
is too small to build Mozc for Android.  To avoid Out-Of-Memory errors,
this CL lets Travis CI use Ubuntu 14.04 Trusty VM instead.

This CL also updates Ubuntu 14.04 Dockerfile to keep those two build
environments as similar as possible.
