Rename getPSUInventoryPath to getPSUInventoryPaths

Rename the utils method/function getPSUInventoryPath() to
getPSUInventoryPaths().  The method/function returns multiple paths in a
vector, so the name should be plural.  This will make the return type
more clear.  Currently the name implies only one path will be returned.

Tested:
* Verified all automated tests build and run successfully
* Verified getPSUInventoryPaths() returns correct data
