Revert "Update Wuffs version"

This reverts commit 42ece2b7c910ac9f769766f11c85feb915879258.

Reason for revert: Requiring the latest version of wuffs broke the flutter roll.

Original change's description:
> Update Wuffs version
> 
> The primary purpose of this commit is to track upstream Wuffs more
> closely.
> 
> A side effect is to pull in the Wuffs commit
> https://github.com/google/wuffs/commit/5bea867f72f5b0ea3dfabfd62435c56d161da1f4
> "Allow an LZW literal width of 1", which eliminates a difference between
> the old third_party/gif decoder and the new third_party/wuffs decoder.
> 
> As the CodecTest.cpp comment says, the GIF spec explicitly says that the
> LZW literal width should be at least 2, but in practice, GIF encoders
> violate the spec. After that upstream commit, Wuffs has followed other
> GIF decoders in being more liberal in what it accepts.
> 
> Codec_InvalidAnimated therefore no longer has a separate "#ifdef
> SK_HAS_WUFFS_LIBRARY" section. The first frame of the test's GIF image
> data, being the required frame of the third frame, no longer has an
> invalid LZW literal width according to Wuffs.
