Fixes &lt;https://issues.guix.gnu.org/61853&gt;.

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.

Previously user-facing commands would happily start building packages
even if they do not support that system.  With this change, all the
user-facing commands reject unsupported packages without going further.

* guix/profiles.scm (profile-derivation): Add #:allow-unsupported-packages?.
Define 'check-supported-packages' and honor #:allow-unsupported-packages?.
* tests/guix-pack.sh, tests/guix-package.sh, tests/guix-shell.sh: Ensure
that unsupported packages are rejected.
* tests/guix-system.sh: Pass "--system=armhf-linux" when attempting to
build gnu/system/examples/asus-c201.tmpl.
