Remove unused _bfd_elf_ifunc_get_synthetic_symtab

Since _bfd_elf_ifunc_get_synthetic_symtab is no longer called by x86
get_synthetic_symtab, it is now unused.  This patch removes it.

	* elf-bfd.h (_bfd_elf_ifunc_get_synthetic_symtab): Removed.
	* elf-ifunc.c (_bfd_elf_ifunc_get_synthetic_symtab): Likewise.
