[golist] Issue #14: golist should handle naming assertions cleanly

[Nicolas Mailhot]

nim reported a new issue against the project: `golist` that you are following:
``
Because the naming of Go projects is a mess many of them (including core Google modules)
have started asserting how they should be named.

This results in golist panics.

Because golist is often called by other scripts (for example, rpm dependency scripts) the
panic messages are unhelpful, because the recipient of those messages has not called
golist directly and does not know what exact golist call resulted in this panic.

golist should handle this case by default and:
1. output useful info to stderr, including what exactly it was doing at the panic time
2. abort with an error code
``
