The "pr" database root directory /var/target should be moved from /var

[gonzoleeman]

The target_core_mod module allows changing the target "database" root directory from the current default of /var/target to another location.

The target_core_mod module allows changing the db directory if and only if no target modules have been loaded,

Since rtslib loads the target_core_mod module, it is the place that needs to be fixed to allow changing this directory.

I looked for a config option for rtslib, but I don't see any. I have a branch that unconditionally changes the directory to /etc/target, but I'm not sure that's the best approach for everybody, even if that will work for me.

Ideas?
