[PATCH V2 1/4] libxl/gentypes.py: don't generate JSON for private type(s)

[Wei Liu <wei.liu2@citrix.com>]

Private types are only useful inside libxl. They don't have a valid JSON
generation function by default.

Currently there's only one private type, that's libxl_ev_link. Not
skipping this field causes testidl to fail as the code generated for
this type is NULL.
