alexa-voiceagent-service: Add patch to fix event argument JSON
In several places in the alexa-voiceagent-service code, strings containing JSON document fragments are put whole into a json-c string object which is added to the event argument json_object, rather than being properly added as built up json-c object hierarchies. The result is an embedded JSON document in a string with extra escaping, which is not usable on the receiving side without knowing that part of the event object effectively needs to be run through a JSON parser to be usable. This is contrary to the voiceagent event documentation and inconvenient for client implementors, so fix it by tokenizing the internal JSON payload string into a json_object tree and passing that as the event argument where necessary. Note that it is ATM not clear if all affected event argument payloads are correct, e.g. LocalMediaSource may need some more work.

+Fix event argument JSON
+
+It was discovered while trying to use some of the capabilities events
+that the argument JSON was incorrectly formatted, with instances of
+all or part of it being double-quoted as strings with escaping. A
+couple instances of this had previously been worked around by hacks
+involving reparsing all or some parts of the arguments a second time
+with a JSON parser, but it seems better to fix it at the source so
+that the events match documentation and are usable as is.
+
+Note that it is ATM not clear if all affected event argument payloads
+are correct, e.g. LocalMediaSource may need some more work.
