ld.so: Add original DSO name if overridden by audit module [BZ #18251]
	* elf/dl-load.c (_dl_map_object_from_fd): Add additional parameter
	for original name of the DSO.  Add it to the name list of the DSO
	if it is actually given.
	(_dl_map_object): Keep track of whether an audit module rewrote
	the file name.  If yes, pass the original name to
	_dl_map_object_from_fd in a new parameter, otherwise NULL.  When
	debugging is enabled, log the change of the file name.
	* sysdeps/mach/hur/dl-sysdep.c: Adjust commented-out call to
	_dl_map_object_from_fd.
	* elf/Makefile: Build and run tst-audit11 and tst-audit12.
