Title: Assume the free space is correct on Travis CI.

As discussed on the list [here](http://news.php.net/php.internals/69429), Travis build machines are heavily loaded and as such testing to see whether disk space decreases after writing a file is not reliable.

This change will fake success on Travis CI based off the TRAVIS environment variable.
