Add falco engine info to --support output

Browse Source 
In some cases, it might be useful to know what falco engine version a
given falco binary supports. We already have a --support option that
prints info about the system, config, rules files, etc.

Add a engine_info object, with an engine_version property containing the
falco engine version in falco_engine_version.h. In the output, it looks
like this:

...
  "engine_info": {
      "engine_version": 8
   },
...
