Clear any warning/error messages set by archive_read_support_compression_*

functions, since we're ignoring their return codes.  This eliminates the
weird behaviour of printing "Using external unxz program for xz
decompression" if an unrelated error occurs when opening an archive (due
to the message lingering in the error message buffer).
