android: Drop never-assigned to LayerRenderer#mPixelBuffer

That member was never assigned a value but only read
from by code claiming to be "used by robocop for testing purposes".

[1] describes Robocop as a UI-level testing framework for Firefox
for Android, which we don't use, so drop the class member and
related test code.
