William Breathitt Gray 706b6aad06 Fix find_path for newer jsoncpp installations
The upstream JsonCpp project has renamed the `json/features.h` file to
`json/json_features.h`. This patch fixes the JsonCpp installation search
by looking for `json/allocator.h` which has not been renamed on newer
versions of JsonCpp.
