Fix guard table creation during startup issue

- Added -hpolicydb to the mysql command in the script
- Made this configurable by utilizing the existing parameters in
xacml.properties for db connections.  No OOM or CSIT changes should be
needed now.

PATCH UPDATE:
	- used Awk to extract property values
	- removed echo except one needed for the base64 command, as far
	as I can tell it is needed when assigning output to a variable,
	I tried to get it to work unsuccessfully.
	- added exit code 2 for missing properties as suggested by Jorge
	and Jim

PATCH UPDATE:
	- remove echo from base64 using Jim's suggestion
	- Added code to remove escape backslashes from properties file,
	I didn't see these locally but when testing in windriver they
	show up in the xacml.properties file on OOM installs
	- More changes per Jorge's latest review
