Disable /dev/shm in CI

According to the Chrome source code (https://chromium.googlesource.com/chromium/src/base/+/master/base_switches.cc#120): The /dev/shm partition is too small in certain VM environments, causing Chrome to fail or crash (see http://crbug.com/715363). Use this flag to work-around this issue (a temporary directory will always be used to create anonymous shared memory files). Addresses gitlab-org/gitlab-ee#4252 but doesn't appear to cure it completely.
