postgis2 2.3.2: make postgis function "ST_GeomFromGeoJSON" work by adding the json-c port as dependency

[mjl-]

Currently, the postgis function ST_GeomFromGeoJSON fails with an error. See below:

testdb=> select ST_GeomFromGeoJSON('{"type": "Point", "coordinates": [-105.01621, 39.57422]}');
ERROR:  You need JSON-C for ST_GeomFromGeoJSON

To reproduce the above error, run the query in any database that has the postgis extension installed ("create extension postgis;").

After applying the attached diff and running ST_GeomFromGeoJSON again:

testdb=> select ST_GeomFromGeoJSON('{"type": "Point", "coordinates": [-105.01621, 39.57422]}');
             st_geomfromgeojson

Attached is an updated Portfile and a diff taking you from current/old Portfile to the attached Portfile.

From what I can gather from earlier trac tickets, postgis+json-c builds were broken in the past. However, that was a long time ago and no longer the case:

I only tested this version/variant: postgis2 @2.3.2_0+postgresql96+raster+topology

Thanks. Matter of fact, I'm going to upgrade to PostGIS 2.4 and take this into account.

Should be done. Please test.
