Packed/unpacked st_rdev transported as 32-bits on OpenIndiana 64-bits

On OpenIndiana 64-bits, st_rdev has major and minor as 32-bits wide each,
but the fuse protocol (common to 32-bit and 64-bit) has an st_rdev field
limited to 32-bit. For now, pack major and minor the same way as in the
32-bit variant (14 and 18 bits).
