MIPS: Wire up clone3 syscall
Wire up the new clone3 syscall for MIPS, using save_static_function() to
generate a wrapper that saves registers $s0-$s7 prior to invoking the
generic sys_clone3 function just like we do for plain old clone.
Tested atop 64r6el_defconfig using o32, n32 & n64 builds of the simple
test program from:
