sched/psi: Select KERNFS as needed
Users of KERNFS should select it to enforce its being built, so
do this to prevent a build error.
In file included from ../kernel/sched/build_utility.c:97:
../kernel/sched/psi.c: In function 'psi_trigger_poll':
../kernel/sched/psi.c:1479:17: error: implicit declaration of function 'kernfs_generic_poll' [-Werror=implicit-function-declaration]
1479 | kernfs_generic_poll(t->of, wait);
Fixes: aff037078eca ("sched/psi: use kernfs polling functions for PSI trigger polling")
