feat(3p): upgrade sbcl to 2.1.2 r/2484

sbcl 2.0.9 introduced a new warning:

> minor incompatible change: the compiler signals a warning at
> compile-time when an initform of T, NIL or 0 does not match
> a STANDARD-CLASS slot's declared type.

This broke a few packages, but they all have been fixed upstream in the
meantime and we only need to bump their versions. The culprits are:

* defclass-std which possibly has become unmaintained since the fix
  (december 2020).

* cl-prevalence which also needs one symbol from bt now

* lisp-binary which also includes a new file now
