Need to avoid conflicts between busybox and netifd

Accept only lines that starts with 'src-git' not just contain that.

Make lists general. Board specific packages are handled by lua not m4
that meanst that we have same lists for all boards and specific sections
are ignored/skipped depending on model variable.

Install seems to be no longer working instead compile works so use
compile instead.

Script should still be run in OpenWRT directory but at the same time
because lists templates are no longer part of it can reach different
directory as a source.
Also removed hack for automatic generation of repositories and replaced
with better implementation in m4 it self.

These packages are also included in base lists so having them in one
another list makes no sense.
