Move expected results for Linux-specific LayoutTests to more generic location

Move expected results for Linux-specific LayoutTests to more generic location

The corresponding tests are only run on Linux, so we can move these
expectations from platform/chromium-linux/platform/chromium-linux/ to
platform/chromium-linux/.

This is a step towards moving platform-specific tests to the generic location.

lgtm

I'm surprised this even works! Makes me even more convinced that having tests
under the platform directory is more confusion than it justifies.
