Optimise tinyipa boot time

Browse Source 
This patch reduces tinyipa boot time significantly by preinstalling all
required system packages at build time instead of the traditional
tinycorelinux method of loading them at runtime, cutting many seconds
of unpacking squashfs files out of the boot procedure.
