libelffile: move to DWARF3 when writing .debug_frame.

zR augmentation in .debug_frame isn't recognized by llvm-dwarfdump.
This leads to below test failure after compiler update:
  DwarfTest.DebugFrame
  DwarfTest.x86_64_RegisterMapping

So switch to DWARF3, which supports 64-bit format without using zR
augmentation.
