blksnap DKMS module not available on Ubuntu 24.04.4 with kernel 6.17.0 for Google Cloud Platform (GCP)

### Distribution Ubuntu 24.04.4 LTS ### Architecture amd64 ### Kernel version 6.17.0 from Ubuntu package linux-image-gcp (6.17.0-1008.8~24.04.1) ### Blksnap version 6.3.2.1207 dkms ### Bug description We wanted to upgrade our Ubuntu packages. But the setup of the kernel failed due to dkms not able to compile the blksnap module. apt output: ``` Setting up linux-headers-6.17.0-1008-gcp (6.17.0-1008.8~24.04.1) ... /etc/kernel/header_postinst.d/dkms: * dkms: running auto installation service for kernel 6.17.0-1008-gcp Sign command: /usr/bin/kmodsign Signing key: /var/lib/shim-signed/mok/MOK.priv Public certificate (MOK): /var/lib/shim-signed/mok/MOK.der Building module: Cleaning build area... make -j2 KERNELRELEASE=6.17.0-1008-gcp -j2 -C /lib/modules/6.17.0-1008-gcp/build M=/var/lib/dkms/blksnap/6.3.2.1207/build modules...(bad exit status: 2) Error!

See https://packages.ubuntu.com/noble/linux-image-gcp for current version of actual package. ### Expected behavior The module compiles with a current Ubuntu kernel. ### Additional information Maybe the same as #106 ?
