Patch UnRAR: allow skipping files in solid archives

This is a cherry-pick of commit 24f225c

Modification to unrar codebase allowing skipping of files within
Solid archives when parsing in extraction mode, enabling us to skip
encrypted files while still scanning metadata and potentially
scanning unencrypted files later in the archive.
