syscalls: Fix offset type of ksys_ftruncate()
After the commit below, truncate() on x86 32bit uses ksys_ftruncate(). But
ksys_ftruncate() truncates the offset to unsigned long.
Switch the type of offset to loff_t which is what do_sys_ftruncate()
expects.
Fixes: 121b32a58a3a (x86/entry/32: Use IA32-specific wrappers for syscalls taking 64-bit arguments)
