Breakpad DWARF Reader: Also look for DWARF in sections with the proper names.

Browse source 
The DWARF specification specifices which names the sections containing
DWARF information should have. OSX uses slightly different names. This
patch changes the DWARF reader to look for the sections under both
sets of names.
