Cannot compile sources including Kbuild-generated files

[lenticularis39]

There are some sources that include sources generated by Kbuild, which are not present in the kernel trees that are only configured.

This prevents DiffKemp from compiling the file drivers/scsi/scsi_sysfs.c in the RHEL 8.x kernels, because it tries to include scsi_devinfo_tbl.c, which is a file generated by Kbuild when building the kernel. This leads to symbols scsi_is_sdev_device and scsi_remove_device being marked unknown and not included in the snapshots.
