s390: Check sreldynrelro in elf_s390_finish_dynamic_symbol

Add check for sreldynrelro being NULL, introduced by commit 5474d94f03ae
("dynrelro section for read-only dynamic symbols copied into
executable") in elf32-s390.c function elf_s390_finish_dynamic_symbol,
also to its elf64-s390.c counterpart.

Found while inspecting and cleaning up differences between elf32-s390.c
and elf64-s390.c.

	* elf64-s390.c (elf_s390_finish_dynamic_symbol): Add
	sreldynrelro check from elf32-s390.c.
