proto: consistently use non-nil, zero-length []bytes for empty bytes strings

The fast-path decoder decodes zero-length repeated bytes values as
non-nil, zero-length []bytes. Do the same in the reflection decoder.

This isn't really a correctness issue, since there's no ambiguity about what a
nil entry in a [][]byte means. Still a good idea for consistency, and
retains v1 behavior.
