Dwarf5 fixes [5 of 5]: Recognize dwp version 5.

Browse source 
Fifth of 5 small patches to fix various breakpad issues found
while testing dump_syms of DWARF v5 in ChromeOS.

DWARF v5 introduces a new dwp version, version 5. The current
dwp reader only recognizes versions 1 & 2 as valid dwp versions. This
CL fixes that.
