Add some speaking prefix to the identifier.

[TASK] Build more PHP modules in travis environment

In order to execute certain unit tests special requirements
of the environment must be met. In particular several
additional PHP modules need to be installed.

Instead of hiding what is added to the environment,
use a helper script to not clutter the travis
configuration file, but at the same time make it
transparent there which PHP modules are built.
