Check for binary content using bytes.Index before building postings

In commit 8029ba ("Include files without text on index"), I bailed
halfway in newSearchableString on finding problems. Unfortunately, the
postingsBuilder was not meant to process a file only halfway. This lead
to OOB access during the rune/byte translation for shards that had
halfway processed files.
