fix(guix): restore preference-injector identity in guix.scm

guix.scm declared (name "squisher-corpus") -- the squisher clobber, which copied
one package definition into many repos carrying the wrong project's identity.
Measured across all 418 estate repos: 45 affected.

Fixes IDENTITY ONLY: name, synopsis, description, home-page, header comment.
The (license ...) form is deliberately untouched -- the licence drift (58 repos
asserting PMPL) is a separate owner decision. Verified byte-identical by md5 of
the licence form before and after.
