mips switch sgtu to sltu for clang in ndk r14

The verion of clang in ndk r14 (3.9) has a built in llvm assembler
that does not have the sgtu pseudo instruction.
sltu is the actual instruction, so switch the 2 operands and use
the instruction instead of the pseudo op.

BUG=libyuv:700
TEST=try bots build mips without error.
