s390/idle: Add missing EXPORT_SYMBOL_GPL()

Browse Source 
Uwe Kleine-König reported this build breakage caused by a recent commit
which provides arch specific kcpustat_field_idle()/kcpustat_field_iowait()
functions:

ERROR: modpost: "arch_kcpustat_field_idle" [drivers/leds/trigger/ledtrig-activity.ko] undefined!
ERROR: modpost: "arch_kcpustat_field_iowait" [drivers/leds/trigger/ledtrig-activity.ko] undefined!

Fix this by adding the missing EXPORT_SYMBOL_GPL().
