[Buildroot] [PATCH 09/16] package/minidlna: improve systemd support

Support running minidlna in system-wide mode using systemd:
1. Set --with-db-path and --with-log-path configure options to make
default minidlna directories comply with FHS.
2. Install suitable minidlna.conf for system-wide mode.
3. Install sysctl.d config file to increase inotify watches count.
4. Install tmpfiles.d config file to mkdir and chmod necessary
directories for minidlna running in system-wide mode.
5. Install sysusers.d config file to create minidlna user when using
systemd.
6. Install minidlna.service for systemd.
Note: User=minidlna should be set in minidlna.service, not in
minidlna.conf, because minidlna is unable to drop privileges correctly
by itself: it does not get any privileges provided by groups of minidlna
user. Systemd drops privileges correctly in that case.
