Subject: [PATCH] Build/Test tools: Get Travis builds working on HHVM again.

This change moves to specifying the PHPUnit version for all PHP versions, and fixes an issue where the Composer global bin directory is not at `~/.composer/vendor/bin` on the boxes that are used for HHVM builds.

See #40100
