Subject: Unexport `CIRRUS_COMMIT_MESSAGE`

Cirrus CI sets this environment variable from the pull request
description.  However it does not seem any locales other than C
are installed, the default external encoding is US-ASCII.  That
means this environment variable will be an invalid byte sequence,
and some tests fail.
