Randomize seed for SkDiscretePathEffect::filterPath()
Fix for https://code.google.com/p/skia/issues/detail?id=2581. Randomizes
the seed in SkDiscretePathEffect::filterPath(). Prior to this we were
using the path length as a seed.
Now, if we have two different paths with identical contents and we
apply an SkDiscretePathEffect to each, we obtain two different random
paths. Previously, we would obtain two overlapping paths (identical
path contents leading to the same seed).
