minidlna: update to latest master

Removed inactive maintainer.

Cleaned up Makefile to remove old options.

Switched to PKG_INSTALL for consistency.

Added PKG_BUILD_PARALLEL for faster compilation.

Fixed license info.

Removed '' from enabled for consistency.

Ran init script through shellcheck. Batched config file writes.

Switched it to use procd. The -S parameter changes it to foreground. It
stands for systemd.

Added a sysctl tweak to get rid of warning.
