microblaze: Fix sys_clone syscall

sys_clone syscall ignored args which this patch mapped to args
which are passing from glibc.

Here is the origin problem description.

"I ran the static libgcc tests (very few of them are there, they are
mostly dynamically linked) and some of  them fail with an assertion in
fork() system call (tid != pid), I looked at the microblaze/entry.S
file and it looks suspicious (ignores arguments 3-5)"

Arg mapping should be:
glibc ARCH_FORK(...) -> do_fork(...)
r5 -> r5   (clone_flags)
r6  -> r6 (stack_start, use parent->stack if NULL)
pt_regs -> r7 (pt_regs)
r7 -> r8 (stack_size)
r8 -> r9 (parent_tidptr)
r9 -> r10 (child_tidptr)
