Most of the fs-verity tests fail if the fs.verity.require_signatures sysctl has been set to 1. Update them to set this sysctl to 0 at the beginning of the test and restore it to its previous value at the end. generic/577 intentionally sets this sysctl to 1. Make it restore the previous value at the end of the test rather than assuming it was 0. Also simplify _require_fsverity_builtin_signatures() to just check for the presence of the file /proc/sys/fs/verity/require_signatures rather than check whether the fs-verity keyring is listed in /proc/keys.
