linux-user: Add support for FS_IOC32_<GET|SET>VERSION ioctls

These FS_IOC32_<GET|SET>VERSION ioctls are identical to
FS_IOC_<GET|SET>VERSION ioctls, but without the anomaly of their
number defined as if their third argument is of type long, while
it is treated internally in kernel as is of type int.
