tests: Adjust to cope with glibc graft.

This is a followup to 1328c4cca531318e3ed90c6aecb522a5b22a4bcc, which
led to failures for tests that were not prepared to cope with that.

* tests/guix-environment-container.sh (hello_drv_nested): Pass “-E
GUIX_BUILD_OPTIONS” so ‘--no-grafts’ is passed.
* tests/guix-pack.sh (GUIX_BUILD_OPTIONS): Add ‘--no-grafts’.
* tests/transformations.scm ("options->transformation, with-graft"):
Skip when ‘glibc-final’ has a replacement.
