rtla/tests: Add runtime tests for restoring continue flag

In case an action preceding the continue action fails, not only
the continue flag should not be set, it should be unset if it was set
from a previous run of actions_perform().

Add a runtime test to both osnoise and timerlat tools that checks that
this works properly by creating a temporary file.
