Hi Guix,

Attached patches update sbcl-nactivitypub and sbcl-njson to 0.0.5 and
1.1.0 respectively. The order I suppose these should be applied in is:
- sbcl-nactivitypub (because it probably fails to build against njson
  1.0.0 right now.)
- sbcl-njson (because it's backwards-compatible with 1.0.0 and doesn't
  influence nactivitypub in any way.)
