ld --help output

It's best if help message output does not contain tabs, since we don't
know tab stop settings or even if tabs are handled by the output
device.  This reverts some 2020-06-23 changes and fixes the csky help
message.

	* lexsup.c (elf_shlib_list_options): Properly format help message.
	(elf_plt_unwind_list_options): Likewise.
	* emultempl/cskyelf.em (PARSE_AND_LIST_OPTIONS): Likewise.
