taskstats: drop the unused CPU_DONT_CARE enum member

Browse Source 
CPU_DONT_CARE was added by the original listener cpumask code in 2006
(f9fd8914c1) and has never had a single user, not even in the
commit that introduced it. It survived every refactor of the listener
path since, including the recent handler folds.

Kill it, twenty years is enough.
