Updates several tests results for accelerated canvas. Affected tests are set as skip to handle both enabling/disabling accelerated canvas. They could be updated after accelerated canvas is enabled until release on Android.
Some skipped reftest failures could be addressed by updating Android emulator to more than or equal to 25.
On Android Emulator, accelerated canvas is set as disabled with mochitest-media "Mochitest media run" and web-platform-tests-wdspec "Web platform webdriver-spec run". Android Emulator does not use hardware GPU. Accelerated canvas handling becomes slow. Then these tests were failed with TIMEOUT.
