Rached Ben Mustapha ba35ca522a Handle pack loading errors in rebuild-index ...

Errors returned from backend.LoadAll() were not handled, leading to
these fatal errors from the unpacker trying to read the size from the end of
an empty buffer:

`seeking to read header length failed: bytes.Reader.Seek: negative position`

This change takes care of returning on error, as well as showing which pack
failed to load and validating pack integrity.
