update php versions to test on (jpfuentes2#575)

* update php versions in .travis.yml

* try container runner

* skip test that fails on php 7+

* set dist: trusty

* try getting hhvm to run on travis

* back to normal builds

* only use trusty for hhvm

* correctly specify environment

* do no longer allow failures for php 7

since all the tests now pass on php 7 we should no longer allow failures

* test memcached

* install memcache for php 7
