Title: Update the return value of FUSE.listxattr

By adding the extra '\x00' character to an otherwise empty string, fusepy makes it look like a file with no extra attributes has one (nameless?) attribute.

xattr {file} prints a blank line,
xattr -l {file} prints "xattr: [Errno 22] Invalid argument: '{file}'"
