[als] Avoid using DATAPIPE_USE_CACHED in brightness re-evaluation. JB#22475

Only place where datapipes are executed without explicitly giving
an input value is when brightness datapipes are re-executed.

As an enabler for dropping otherwise unneeded parameter, rewrite
the re-execution so that it explicitly provides current value as
input.
