errors: detect unknown frames correctly (#192)

With Go 1.12, we will now be doing mid-stack inlining. This exposes
inlined frames to runtime.Callers and friends.

The spec says that a runtime.Frame may have a nil Func field for
inlined functions. Instead, use the Function field to detect whether
we really have an empty Frame.
