debugedit: Do not 'edit_dwarf2' when just extracting build-id

No need to call edit_dwarf2() if debugedit is invoked just to extract
build-id (with `-i -n'). Otherwise, we will get `DWARF version 0
unhandled' warning for compressed .debug files:

  /usr/lib/rpm/debugedit: ./usr/lib/debug/...e.ko.debug: DWARF version 0 unhandled

Context: We have kernel modules elfcompressed in ALT.
