Subject: [PATCH] utils: Exclude Open CAS modules from dracut initramfs image

Open CAS modules are not intended to be included into initramfs, and so
CAS upgrade does not trigger initramfs rebuild. This may lead to loading
old Open CAS modules if they were included into initramfs image. Explicitly
excluding them from initramfs image effectively addressed this issue.
