Sultan Alsawaf d4bbaf5715 sched/core: Forbid Unity-based games from changing their CPU affinity 
Unity-based games (such as Wild Rift) like to shoot themselves in the foot
by setting a nonsense CPU affinity, restricting the game to a narrow set of
CPU cores that it thinks are the "big" cores in a heterogeneous CPU. It
assumes that CPUs only have two performance domains (clusters), and
therefore royally mucks up games' CPU affinities on CPUs which have more
than two performance domains.

Check if a setaffinity target task is part of a Unity-based game and
silently ignore the setaffinity request so that it can't sabotage itself.
