dracut: Add a new dracut module for gcp udev rules

[ravanelli]

• The dracut module is required for ignition (https://github.com/coreos/ignition) to work when using Redhat/Fedora CoreOS in GCP. Since the rules are kept in this repository, makes sense for the module to be part of it as well for a better maintenance in case the rules change;
• Modify the spec file to include the new dracut module.

Hi @ravanelli. Thanks for your PR.

I'm waiting for a GoogleCloudPlatform member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

F.Y.I I only tested the changes for google-compute-engine.spec in F38. I didn't validate the changes for debian. Would be good if something could double check it ;) I'm not too familiar with debian packaging.
