sched: fix !SYSFS build breakage

When CONFIG_SYSFS is not set, CONFIG_FAIR_USER_SCHED fails to build
with

kernel/built-in.o: In function `uids_kobject_init':
(.init.text+0x1488): undefined reference to `kernel_subsys'
kernel/built-in.o: In function `uids_kobject_init':

kernel/built-in.o: In function `uids_kobject_init':
