Skip extra relocations in .rel.plt/.rela.plt 

Extra relocations may be added to the .rel.plt/.rela.plt section, which
are unrelated to PLT.  We should skip them when retrieving PLT entry
symbol values.

	PR binutils/18437
	* elf32-i386.c (elf_i386_get_plt_sym_val): Skip extra relocations
	in .rel.plt/.rela.plt.
	* elf64-x86-64.c (elf_x86_64_get_plt_sym_val): Likewise.
