Task logs are delayed

[droyad]

The sensitive value masking currently does not release log lines until it finds a line that is definitely not a partial match for a sensitive value. i.e a line that ends with a character that none of the sensitive values start with.

This is generally not noticeable as the number of sensitive values tends to be small. Their starting letters typically not cover a large portion of the alphabet or typical line endings (e.g. '.'). Chances are the lines get flushed sooner or later.

With a change introduced for #6604 a lot more values are being considered as sensitive for Linux targets.
