PR 30060, ASAN error in bfd_cache_close

After bfd_close nothing should access bfd memory.  Now that bfd_close
always tidies up even after an error, attempting to tidy the cached
bfd list by calling bfd_cache_close is wrong and not needed.

	PR 30060
	* ar.c (remove_output): Don't call bfd_cache_close.
	(output_bfd): Delete.
	* arsup.c (ar_end): Call bfd_close_all_done, not bfd_cache_close.
