eventscripts: Fix statd-callout update handling
60.nfs and 60.ganesha touch $statd_update_trigger every time they're
run. This stops the statd-callout updates from ever being called.
Make this logic self-contained and move it to new function
nfs_statd_update() in the functions file. Call this in 60.nfs and
60.ganesha with the appropriate update period as the only argument.
