Revert "packages, fhs: fix saxon includes/excludes expression"

This reverts commit 9ddc482591a557ef2b363b9c6738dd2007879ff6.

Taking the saxon jars off of the classpath stops the privilege-xacml
client from finding a class.
dcache-core, alarms: restore xml connector to initialization properties

A recent refactoring (http://rb.dcache.org/r/6541) of the connector initialization for the alarms appender inadvertently eliminated the url property for the xml datanucleus plugin.

This patch restores it.

(Note: This is my fault, as I acked that patch and should have noticed it).
