Fix OpenZFS build issue for Debian Bookworm

dkms package layout is changed in bookworm and splits into dh-dkms
package. Debhelper in Bookworm is updated to use dh-sequence-dkms
instead of dkms.

GitHub Actions are updated to use Ubuntu 22.04 instead of Ubuntu
20.04, since dh-sequence-dkms is not aavailable on Ubuntu 20.04.
