Kernel+LibC: Pass 64-bit integers in syscalls by value
Now that support for 32-bit x86 has been removed, we don't have to worry about the top half of `off_t`/`u64` values being chopped off when we try to pass them in registers. Therefore, we no longer need the workaround of pointers to stack-allocated values to syscalls. Note that this changes the system call ABI, so statically linked programs will have to be re-linked.
