[PATCH] sysctl: delete unused define SYSCTL_PERM_EMPTY_DIR

["Thomas Weißschuh" <linux@weissschuh.net>]

It seems it was never used.

Fixes: 2f2665c13af4 ("sysctl: replace child with an enumeration")

This was originally part of the sysctl-const series [0], but it doesn't
really belong in there.
To slim down that series as much as possible, submit this patch on its
own.
