scroggo f174e92873 Update libwebp and resume testing scaled webp 
libwebp has a fix for [1]. Update to the commit that contains the fix.

Update libwebp.gypi, corresponding to libwebp's latest makefile.

Turn back on DM testing for scaled webp, now that it should no longer
use uninitialized memory.
