Blacklist SKPs for the 100k_IMG_DECODE bot

Started failing due to https://skia-review.googlesource.com/c/5758/
Explanation from scroggo@:
"""
The problem is that the image is truncated before receiving the color
table, which I recently changed (here) from resulting in
kIncompleteInput (which get_images_from_skps determines to be okay) to
resulting in kInvalidInput (which is a failure).

I downloaded the failed image (attached), and it looks as expected
(truncated prior to the color table).
