FS-8398: Added event_handlers/mod_amqp to avoided modules for Ubuntu 14.04 Trusty

This change makes it so that event_handlers/mod_amqp is avoided when building
debian packages for Ubuntu 14.04 (Trusty). If this module is packaged there is
a dependency issue related to the rabbitmq libraries.

Avoiding the module was the simplest solution to achieve debian packaging on the
Ubuntu 14.04 OS.
