Use std::abort() instead of exit().

libFuzzer can intercept the abort call and print out the stack leading
to the failure. That is not the case with exit().

Test: SANITIZE_TARGET="address coverage" make vts -j64 && vts-tradefed
run commandAndExit vts --skip-all-system-status-check --primary-abi-only
