Fix overflow issue in approx_exp2().

skcms' vector implementation of approx_exp2() used a clever bit-
twiddling trick to generate its results. Unfortunately, the bit trick
fails for large inputs and generates a nonsense result. This is now
fixed with a well-positioned call to min_.

This fix parallels a similar fix in skvm, http://review.skia.org/497283
