Subject: [PATCH] Update jcw-gen to work with interfaces in typemaps

Context: ebd7d76161ac60ce7ad3bfee87789f08a333ae78

ebd7d761 introduced support for interfaces in typemaps, but it failed
to update the `jcw-gen` utility to ignore them when generating Java
Code Wrappers.  This, in turn, made Xamarin.Android fail to build.

Fix the issue by ignoring interfaces in `jcw-gen`
