bzip2: fix bunzip2 -qt returns 0 for corrupt archives

"bzip2 -t FILE" returns 2 if FILE exists, but is not a valid bzip2 file.
"bzip2 -qt FILE" returns 0 when this happens, although it does print out
an error message as is does so.

This has been fix by Debian, just port changes from Debian patch file
"20-legacy.patch".
