basic_pre_script.inc already identifies the disk holding OEMDRV
($SYSDRIVE). Write its short name to /tmp/disk-include.cfg after the
GPT check so both cinnamon and KDE profiles can %include it instead of
the hardcoded 'ignoredisk --only-use=sda,nvme0n1' that fails on
systems without an NVMe drive (or without sda).
