  Parse all DWARF source files in DwarfWalker::buildSrcFiles

>From 2.6.4.16 of the DWARF5 standard

	Prior to DWARF Version 5, the current compilation file name was not
	represented in the file_names field. In DWARF Version 5, the current
	compilation file name is explicitly present and has index 0. This is
	needed to support the common practice of stripping all but the line
	number sections (.debug_line and .debug_line_str) from an executable.
