misc: examples: IMS PCSCF pcscf.cfg update

Minor changes to make the example functional in the current stable release and higher.

- Load WITH_IPSEC by default (IPsec module is required for IMS Usrloc to load)
- Bind to any IP in example
- Removed con=> prefix on MySQL Connection (not used in single instance / if not clustered)

(cherry picked from commit decd184)
