sched/rt: fix build error when CONFIG_SYSCTL is disable
Avoid random build errors which do not select
CONFIG_SYSCTL by depending on it in Kconfig.
This fixes the following warning:
In file included from kernel/sched/build_policy.c:43:
At top level:
kernel/sched/rt.c:3017:12: error: ‘sched_rr_handler’ defined but not used [-Werror=unused-function]
3017 | static int sched_rr_handler(struct ctl_table *table, int write, void *buffer,
| ^~~~~~~~~~~~~~~~
kernel/sched/rt.c:2978:12: error: ‘sched_rt_handler’ defined but not used [-Werror=unused-function]
2978 | static int sched_rt_handler(struct ctl_table *table, int write, void *buffer,
