squashfs: add setlease file operation

Add the setlease file_operation pointing to generic_setlease to the
squashfs file_operations structures. A future patch will change the
default behavior to reject lease attempts with -EINVAL when there is no
setlease file operation defined. Add generic_setlease to retain the
ability to set leases on this filesystem.
