From: Peter Maydell <peter.maydell@linaro.org>

In commit 52a21689cd829 we added a workaround for a bug in older
versions of htags where they fail with a weird error message if the
environment is too large.  However, we missed one variable which
gitlab CI can set to the body of the commit message:
CI_COMMIT_DESCRIPTION.

Add this to the variables we unset when running htags, so that
the 'pages' job doesn't fail if the most recent commit happens
to have a very large commit message.
