Scopes NODECONSTRUCT_1 from flags_1 to obj_flags (#80104)

This flag only worked on the `/obj/structure` and `/obj/machinery`
level, so let's rescope it from `flags_1` and put it where it belongs -
`obj_flags`.
Bitflag operators should be scoped to their subtype specific bitfield,
not really useful to have this take up a spot on the `/atom` level if
absolutely nothing other than `/obj`s use it.
