[committed, darwin]: adjust output of -P compact_unwind

[Tristan Gingold]

Hello,

this is a minor patch for objdump -P compact_unwind on Mach-O: the stack offset of indirect
entries is now multiplied by the factor so that the displayed output can be directly
interpreted.

Committed on trunk.

Tristan.

binutils/
	* od-macho.c (dump_unwind_encoding_x86): Set the factor.
	(dump_exe_compact_unwind): Change the condition.  Improve
	indentation.
