Temporally disable tombstone tests

Ramdump is temporarily disabled for all target
because recent crashkernel changes enables ramdump
only when the debug policy explicitly says so.

Temporarily disables tombstone tests for all target
until lab devices get new debug policy
which will enable ramdump on userdebug build.

Bug: 243630590
Test: No presubmit fail
