linux-user: Add support for FS_IOC_<GET|SET>VERSION ioctls
A very specific thing for these two ioctls is that their code
implies that their third argument is of type 'long', but the
kernel uses that argument as if it is of type 'int'. This anomaly
is recognized also in commit 6080723 (linux-user: Implement
FS_IOC_GETFLAGS and FS_IOC_SETFLAGS ioctls).
