Subject: drop_monitor: Require CAP_NET_ADMIN for drop monitor configuration
Patch-mainline: v5.4-rc1
Git-commit: c5ab9b1c41f6d89d84fe147e51fe623f90bd026c
References: bsc#1154353

Currently, the configure command does not do anything but return an
error. Subsequent patches will enable the command to change various
configuration options such as alert mode and packet truncation.

Similar to other netlink-based configuration channels, make sure only
users with the CAP_NET_ADMIN capability set can execute this command.
