Reland "Disable some LayerTreeHostBlendingPixelTest on Linux, because flaky."

This is a reland of bd08401c92882ed1c69503217a67b17274439621
(Note that the original CL is no longer in the tree; it landed during yesterday's
Gerrit outage and was reset out of existence. So this is the first time it has
"officially" landed in the tree.)
