test: port the w6a ELF-object observers to ww

Browse Source 
elfobj_test.ww (test/object, on testenv) absorbs 500_w6a, 510_dataw,
and 520_datar: ELF64 header magic/class over the 4 inline programs,
DATAW section/symbol layout plus the 6-section no-DATAW legacy
invariant 991 depends on, and the DATAR .rela.data reloc through
link and run. Strengthened: the reloc symbol is resolved to
'greeting' (declared but never implemented in the C carrier).
