elfclassify: Add --has-debug-sections classification option

There is --unstripped but that is whether the ELF file can be stripped
(further) by removing any .[z]debug_* sections or symbol table
(.symtab section).  The --has-debug-sections option only checks
whether there are .[z]debug sections present.

	* src/elfclassify.c (is_has_debug_sections): New function.
	(enum classify_check): Add classify_has_debug_sections.
	(check_checks): Add and print (if verbose)
	classify_has_debug_sections value.
	(main): Add ar-member to options. Update argp.doc to explain
	different debug options (--unstripped, --has-debug-section and
	--debug-only).
	* tests/run-elfclassify.sh: Add various --has-debug-sections
	tests.
