dwarf2: Use octets for dwarf2 headers

The content of the dwarf2 sections .debug_line, .debug_aranges and
.debug_info starts with an u32 containing the the size of the remaining
data.  According to the dwarf2 specification this value must be expressed
in octets instead of bytes.

	* dwarf2dbg.c (out_debug_line): Use octets for dwarf2 headers.
	(out_debug_aranges, out_debug_info): Likewise.
