generic/484: add _require_xfs_io_command "syncfs"

When using old xfsprogs version, xfs_io doesn't support syncfs command.
It was not fixed until xfsprogs commit eb24bcffc0("xfs_io: fix missing syncfs command").
Add a require for this so that we can skip this case if xfs_io doesn't
support syncfs command.
