With 'set -e', a return status inverted with '!' does not cause the shell to
exit immediately.  Instead use '&amp;&amp; false' to indicate an expected failure.

Fixes a regression introduced in
68380db4c40a2ee1156349a87254fd7b1f1a52d5, whereby the tarball's root
entry is now read-only, due to the creation of "profile-directory" in
the store.

* tests/guix-pack.sh: Remove and recreate $test_directory before
transformation option test.
* tests/guix-pack-relocatable.sh: Add "chmod +w $test_directory" lines
before attempts to write to it.
