If there is no PLT in output, return 0 for first_plt_entry_offset and
plt_entry_size.

	PR gold/20245
	* i386.cc (Target_i386::first_plt_entry_offset): Return 0 if
	plt_ is NULL.
	(Target_i386::plt_entry_size): Likewise.
	(Target_x86_64<size>::first_plt_entry_offset): Likewise.
	(Target_x86_64<size>::plt_entry_size): Likewise.
