Linux_android_emu external_textures_integration_test flakey #192748
Description
This test was recently fixed so it wasn't failing in bringup, but it appears to be flakey:

This turned from flaky to consistently failing.
Dashboard: https://flutter-dashboard.appspot.com/#/build?repo=flutter&branch=master&taskFilter=linux_android_emu+external_textures_integration_test
Build #3033: Success
Build #3034: Flaky, failed on first run and succeeded on second run
Build #3035: Fails
Consistently fails for all subsequent builds.
Note that Build #3035 is a backfill, on an older commit than #3033 and #3034. So this starting to failing consistently doesn't seem related to a specific commit, but instead it started at a certain time.

Leaving a c:flake and higher priority for now . If we downgrade this to P2, we should just remove the test rather than leave it supressed.
Changes the tolerances for frame_rate_main_test.dart. (flutter#196304)
