libwebp: fix vp8 encoder mem alloc offsetting
...
'mem' was being offset once by DO_ALIGN() then shifted 'nz_size' which
would end up accounting for more than ALIGN_CST and exceed the allocation.

Further reduce memory to decode lossy+alpha images

Earlier such images were using roughly 9 * width * height bytes for
decoding. Now, they take 6 * width * height memory.
