systemd/dracut-iniqueue - continue waiting if any timeout script makes progress

A number of timeout scripts can be registered.  If any one of them
makes progress - e.g. assembles a degraded md array - then
the main loop should wait a bit longer rather than pressing forward.

This is particularly important is resume-from-hibernate requires a
degraded md array.  Both the script to forcibly assemble the md array
and the script to abort hibernation if the device doesn't appear
are 'timeout' scripts.  There needs to be a reasonable delay between
these running.

So: if any script has indicated that progress was made, break of out
the loop and go back to normal waiting.
