linux-user: Use correct type for FIBMAP and FIGETBSZ emulation

Browse Source 
Both the FIBMAP and FIGETBSZ ioctl get "int *" (pointer to 32bit
integer) as argument, not "long *" as specified in qemu.  Using the
correct type makes the emulation work in cross endian context.

Both ioctl does not seem to be documented. However the kernel
implementation has always used "int *".
