feat(3p/lisp/sclf): build using buildLisp r/2811

Adding the default.nix is quite straightforward, however we have to make
today's SBCL happy: due to package locking it no longer likes sclf using
an sb-impl internal constant for some reason. This is however a good
opportunity to clean up the stat-*-time code: It converted the times in
an implementation specific way even though time.lisp does provide a
generic way to convert between unix and universal time. Note that the
updated ASDF file is untested, but should be a trivial enough change.
