Only check for OS specific bad filenames when unpacking
When converting a SquashFS image to a tarball, it makes no sense to refuse conversion if the filename is considered evil by the OS. This patch adds an option to is_filename_sane to check if the OS has a problem with the given file name. sqfs2tar sets it to false and converts everything while rdsquashfs sets it to true when unpacking.
