Fix: Chrome headless on docker

[ylecuyer]

Hello, I'm migrating our jasmine integration from the legacy ruby version to the latest javascript version. Everything was working well until I moved the test suite to docker (gitlab CI), here chrome headless wasn't working:

root@d131d44a7f93:/app# ./node_modules/jasmine-browser-runner/bin/jasmine-browser-runner runSpecs --config=spec/javascripts/support/jasmine.json --browser=headlessChrome
Jasmine server is running here: http://localhost:42071
Jasmine tests are here:         /app/spec/javascripts
Source files are here:          /app/public/assets
Running tests in the browser...

    '#11 0x562b164c7333 <unknown>\n' +
    '#12 0x7f4768c1a4a4 start_thread\n'
}

This is because --disable-dev-shm-usage is missing from the options sent to chrome when starting

With the proper option it works as expected:

Thanks for your contribution. This might actually fix some occasional CI failures I've seen.

Would you mind adding a comment explaining what the flag is for and squashing your commits:? If you're not comfortable squashing I can do it for you, but in that case GitHub won't show the PR as merged.
