Clean up import blocks in zabbix module
Clean up import blocks in zabbix module

The salt imports were moved to a try/except block and they shouldn't be.

As a result of cleaning up that import block, this PR does the following:
- moves the salt imports out of the try/except
- updates the __virtual__() function to no longer rely on the status of the salt imports
- updates the old utils paths with the new utils paths
