Properly handle note sections and segments

When dumping notes, get note alignment from either note section or note
segment.  To support notes generated by assemblers with

https://sourceware.org/bugzilla/show_bug.cgi?id=22492

we treate alignment as 4 bytes if it is less than 4.  Otherwise, we skip
notes if alignment isn't 4 nor 8 bytes.

We should call load_separate_debug_file only if e_shstrndx != SHN_UNDEF.

	PR binutils/22490
	* readelf.c (process_notes_at): Add an argument for note
	alignment.  If note alignment is less than 4, use 4 byte
	alignment.  Otherwise, skip notes if alignment isn't 4 nor
	8 bytes.
	(process_corefile_note_segments): Pass segment alignment to
	process_notes_at.
	(process_note_sections): Pass section alignment to
	process_notes_at.
	(process_object): Call load_separate_debug_file only if
	e_shstrndx != SHN_UNDEF.
