.travis.yml: Build esp-open-sdk, based on .travis.yml from esp-open-rtos.travis-esp8266

Before picking esp-open-rtos', I tried to add corresponding steps to
standard MicroPython's .travis.yml, but it just doesn't work in that
configuration (sudo: yes is the biggest difference), with completely
senseless errors popping up, and working them around turns into very
time consuming firefighting.
