MOESSBAUER, Felix Sept. 24, 2026, 6:45 a.m. UTC 
We currently fully expand S before passing it to do_unpack. This makes
all packages that depend on the apt fetcher not cacheable, as the
absolute path ends up in the sstate signatures. Instead, we now use the
unexpanded bitbake variable ${S}.

Fixes: 37cb017a ("Convert apt source fetcher into native ...")
