packages: Better preserve object identity when rewriting.
Fixes a bug whereby the presence of propagated inputs could lead to two
non-eq? but actually equal packages in a bag's inputs. The problem
would manifest itself when running, for instance:
guix build inkscape -d --with-graft=glib=glib-networking --no-grafts
The resulting derivation would differ due from that without
'--with-graft'. This was due to the fact that glib propagates libffi;
this instance of libffi was not rewritten even though other instances in
the graph were rewritten. Thus, glib would end up with two non-eq?
libffi instances, which in turn would lead to duplicate entries in its
'%build-inputs' variable.
Fixes <https://bugs.gnu.org/43890>.
* guix/packages.scm (package-mapping)[rewrite]: Remove call to 'cut?'
and call 'replace' unconditionally.
[replace]: Add 'cut?' case.
* tests/guix-build.sh: Add test combining '--no-grafts' and
'--with-graft'.
* tests/packages.scm ("package-input-rewriting/spec, identity")
("package-input-rewriting, identity"): New tests.
