dwarf_loader: Ignore top level DW_TAG_dwarf_procedure tags 

We also ignore it when it appears inside a DW_TAG_subprogram, so just
don't emit the warning that it is not supported when it appears in the
top level.

So far it doesn't look useful for what these tools do, need to revisit
it when the need arises.
