minidlna: Move sysctl config to /etc/sysctl.d/50-freedombox.conf
/etc/sysctl.conf is owned by procps package.

Test: Run minidlna install on fresh image.
- /etc/sysctl.conf is not modified.
- /etc/sysctl.d/50-freedombox.conf has the expected content.
- /proc/sys/fs/inotify/max_user_watches contains 100000.

- Running with these changes upgrades app version and triggers a setup. Changes
in /etc/sysctl.conf are removed. After undoing the changes /etc/sysctl.conf is
identical to pristine version installed from procps package. This can be
obtained by running; rm -f /etc/sysctl.conf ; apt install --reinstall procps -o
Dpkg::Options::=--force-confmiss

Closes #1802.
