Remove install-phpunit.sh

The default fetch location is PEAR, which is not where PHPUnit
is distributed from anymore. apt-get and yum tend to ship horribly
outdated versions of PHPUnit that we don't want. Macports? Lol.

Instead one should install PHPUnit via composer. If you use vagrant
for testing, this is done for you. Our composer.json also lists
PHPUnit if you want to do it yourself.
