FIX sysctl configuration directory

man sysctl.d:
...
Packages should install their configuration files in /usr/lib/. Files in
/etc/ are reserved for the local administrator, who may use this logic to
override the configuration files installed by vendor packages. All configuration
files are sorted by their filename in lexicographic order, regardless of which
of the directories they reside in. If multiple files specify the same option,
the entry in the file with the lexicographically latest name will take
precedence. It is recommended to prefix all filenames with a two-digit number
and a dash, to simplify the ordering of the files.

If the administrator wants to disable a configuration file supplied by
the vendor, the recommended way is to place a symlink to /dev/null in the
configuration directory in /etc/, with the same filename as the vendor
configuration file.
