sysctl: fix unused proc_cap_handler() function warning

Since usermodehelper_table() is marked static now, we get a
warning about it being unused when SYSCTL is disabled:

kernel/umh.c:497:12: error: 'proc_cap_handler' defined but not used [-Werror=unused-function]

Just move it inside of the same #ifdef.
