All ELF backends with shared library support need to add dynamic tags.
Add dt_pltgot_required and dt_jmprel_required to elf_link_hash_table to
indicate that DT_PLTGOT and DT_JMPREL are required dynamic tags.
1. Add _bfd_elf_add_dynamic_tags to add common dynamic tags.
2. Add _bfd_elf_maybe_vxworks_add_dynamic_tags to add common VxWorks
dynamic tags.
