 In order to make unzip build reproducibly, we remove the
 (already optional) build date from the binary.

Addresses &lt;https://issues.guix.gnu.org/62406&gt;.

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.

With commit bbcd06e56c06376e640a7ac81a7109e7135a20f2, the command
"guix package -s '^fileutils$'" would match the 'ocaml-fileutils'
package, because its 'package-upstream-name*' is "fileutils".  Work
around it.

Reported by Vagrant Cascadian.

* tests/guix-package.sh: Change "fileutils" example to use a different
package name.
