1. tz: add TimeZone::try_system …

   This API is like `TimeZone::system`, but turns "get system configured
   time zone" into a fallible operation instead of automatically falling
   back to UTC.
   
   The error message here is pretty generic and uninformative. All of the
   interesting bits are emitting as log messages. In #65, I talked about
   improving this, but it's not quite clear the best way to do that. I
   think we'd probably need to invent some smarter infrastructure for
   collecting a "trace" of what was attempted, and then either emit them as
   log messages or tie them up into a single error message. But the latter
   case could result in a very big error message.
   
   So for now, this just returns a pretty generic error message, but all of
   the log statements are still there for when you need to understand more
   deeply what went wrong.
