Disable SaveForBugreport_Triggers on android builds

This test seems failing on GSI builds for non clear reasons.
The code under test does not depend on kernel feature and
other nearly-identical tests are not failing, nor this test
seems failing on other devices.
Unfortunately the bug is very unactionable, I did not
find a way to look at logs for the other tests (especially
the SaveForBugreport_WriteIntoFile, I don't see how that
wouldn't fail either as it's practically identical).
Given this is a non-critical feature I don't see too many
other options than disabling the test for now.
