[PATCH] bundle: improve message when unknown hash algorithm detected

["brian m. carlson" <sandals@crustytoothpaste.net>]

The current code states "unknown hash algorithm length".  This is
slightly confusing, and moreover, we've gotten feedback that it's hard
to translate into other languages.  Since the case is that we cannot
detect the hash algorithm, let's just say that.  This is clearer and
more direct, reflects the intent of the code (which calls the function
detect_hash_algo just a few lines above), and will be easier to
translate.

Matthias contacted me privately about this message and I thought since
we're still in the RC period, it would make sense to include this in to
help translators and those who aren't native speakers.
