autotest.sh broken if PHPUnit is installed using a script as facade

[LukasReschke]

If PHPUnit is installed using a script as facade invoking it will fail, in my case this means:

➜  master git:(master) ✗ which phpunit
/usr/local/bin/phpunit
➜  master git:(master) ✗ cat /usr/local/bin/phpunit
#!/usr/bin/env bash

/usr/bin/env php -d allow_url_fopen=On -d detect_unicode=Off /usr/local/Cellar/phpunit/4.6.4/libexec/phpunit-4.6.4.phar $*%

Invoking php /usr/local/bin/phpunit will fail hard now. As it is a shell script and not a PHAR file.

Regression caused by #16045
