Set DTSF_PLUGIN if needed when compiling from dtb

Browse source 
The need for the plugin flag is determined by the existence of __fixups__
or __local_fixups__.

This is a bit simplifying because if __fixups__ or __local_fixups__
exist but don't have properties, the plugin flag isn't needed. But in
practise the test should be good enough such that this corner case
doesn't matter.
