MIPS: Fix Run_Wasm_F32CopySign

MIPS: Fix Run_Wasm_F32CopySign.

Run_Wasm_F32CopySign was failing because function copysign
that is used to verify the results does implicit conversion
from float to double. In this conversion we lose information
about NaN sign and the test fails.

Fix by using copysignf to avoid unnecessary float to double
conversion.
