aw: Disable testGetContentHeight CTS test

My fix aosp/943625 didn't make the new release, it only reached dev
repo, we need to disable this test until next release.

Bug: 967173
Test: android_webview/tools/run_cts.py -f=android.webkit.cts.WebViewTest#testGetContentHeight --cts-release O, test didn't run.
Test: android_webview/tools/run_cts.py -f=android.webkit.cts.WebViewTest#testGetContentHeight --cts-release N, test didn't run.
