Remove the tests sub-directory

The tests sub-directory was directly inherited from Fedora to run the
upstream Toolbx system tests as part of a downstream CI.  It doesn't
work with CentOS Stream 10 because it uses packages that are missing
(eg., bats), and leads to:
  run_bats_tests.sh: line 52: bats: command not found

This is currently preventing CentOS Stream 10 merge requests from
passing the CI.  It's better to remove them until the tests are adjusted
to work with CentOS Stream 10.

Resolves: RHEL-97099
