vm: test for abort condition of current invocation

When a vm script aborted after a timeout/signal interruption, test
whether the local timeout/signal watchdog was responsible for
terminating the execution.

Without this, when a shorter timer from an outer `vm.run*` invocation
fires before an inner timeout, the inner timeout would throw an error
instead of the outer one, but because it did not witness the timeout
itself, it would assume the termination was the result of a signal
interruption.
