packaging: Creating keystore for jboss use

Currently jboss uses apache.p12 keystore file. In cases
where apache is not used for proxying, jboss tries to
use this file directly and fails on permissions.

This patch tries to resolve the issue by adding an additional
keystore jboss.p12 during setup/upgrade for the use by the jboss.
