scripts: Change here document delimiters

Fix the outstanding scripts using non standard shell here document delimiters.

This should have been caught by
https://github.com/kata-containers/tests/pull/3937, but there is a bug
in the checker which is fixed on
https://github.com/kata-containers/tests/pull/4569.

Fixes: #3864.
