sbcl: support using CLISP as bootstrap host

Moves the bootstrap code into main derivation because it’s only used there, and
this helps let the main derivation decide when to evaluate it in the first
place (depending on the system), which helps on Hydra.

Not actually enabled by default on any systems yet.
