Specify linux headers dependencies in control file

It seems that this PR is causing the CI pipeline to fail.

@ixhamza that is probably because these packages are not available when you build the debian package in github CI but when you actually build openzfs in our environment, these are required afaik as openzfs was marked as being a kernel module which basically means it needs these packages to build.
The proper fix is to have these dependencies specified in the package's control file and not do them in the builder, earlier it was done for a different reason which is no longer valid. I think we should probably update the CI to either pull the debian packages from somewhere ( we would need to host these ) or maybe do some magic in the CI to remove these deps and then build and test with standard linux image headers ?

How about updating the control file from prebuildcmd for openzfs and openzfs-dbg in build.manifest from scale-build?

I think that would be a better approach. We can keep this repo and CI clean, and building and installing OpenZFS packages would not require installing TrueNAS Linux kernels and headers. We already update debian/control.modules.in for openzfs-dbg in build.manifest.

As long as these get added in build and install time dependencies in openzfs control file (whether here or in scale build), i am fine with it. @usaleem-ix can you do the honours please ?

Sure, I will create a ticket for it and assign to myself.
