Wolfgang Walther cf127c9dc3 treewide: load structured attributes in all bash builders consistently
It's hard to put the sourcing of ./.attrs.sh into all builder
consistently - mistakes will happen. Thus, load structured attrs once in
make-derivation and then source the remaining builder on top.

This should fix quite a few builders with structured attributes in
principle. Most importantly it helps substitute / substituteAll, which
are required for bootstrap on some platforms.
