Make JSONPath.sh use the MOK shell programming style.

[mclarkson]

Describe the bug JSONPath.sh has been imported to remove nasty sed lines from the mokctl code, but JSONPath.sh pollutes the global namespace.

To Reproduce Look at the top of JSONPath.sh. It pollutes the global namespace.

Expected behavior Its global variables should be in the MOK shell style - in an associative array.
