Don't pass around expld.dataseg pointer

The better to see any code that accesses expld.dataseg.

	* ldexp.c (fold_segment_end): Remove seg parameter.  Adjust calls.
	(fold_segment_align, fold_segment_relro_end): Likewise.
	* ldlang.c (lang_size_segment): Likewise.
	(lang_size_relro_segment_1, lang_find_relro_sections_1): Likewise.
