[travis] Switch to Vincit/travis-oracledb-xe installer (#727)

Source: https://github.com/Vincit/travis-oracledb-xe
Author of the instaler, @elhigu, received permission from Oracle
to release this installer for use with Travis CI and others:
wnameless/docker-oracle-xe-11g#118 (comment)

Switch from apt-fast to apt-get.
Due to issues with certificate and/or keyserver,
installation of apt-fast has often been failing.
