Apparently this causes problems with migration.

More specifically:

# There appears to be a bug in the s390 hardware-accelerated version
# of zlib distributed with Ubuntu 20.04, which makes our test
# /i386/migration/multifd/tcp/zlib hit an assertion perhaps one
# time in 10. Fortunately zlib provides an escape hatch
# where we can disable the hardware-acceleration entirely by
# setting the environment variable DFLTCC to 0. Do this on all
# our CI which runs on s390 hosts, both our custom gitlab runner
# and also the Travis hosts.


...speaking of which, this patch seems to only be
touching the gitlab CI and not the travis config.

thanks
