fix: LED driver for every kernel on a fresh install

The DKMS override was written to /etc/dkms before dkms was installed, when that folder doesn't exist yet: the write failed silently and other kernels (e.g. LTS) built against the running one and failed. Create the folder first and stop on a failed write. VERSION 0.9.1.
