Disable generation of tombstone on an ANR The commit: I5b78ce62b26f25d3dc14097e2988ba12c2d77826 (creating seperate files for ANRs traces) provided the following two debug capabilities: (1) renames traces.txt and (2) generates tombstones(for native traces) The second functionalatity is not needed any more since the traces.txt now includes the native traces as well. Generating tombstones for system server causes framework reboot and that should be avoided. This change will prevent dumping of tombstones during ANR.
