1. perf(drm): group dracut_instmods calls …

   This module loops over many bus devices, and calls `dracut_instmods` for each
   one. E.g., on a Lenovo Thinkpad laptop:
   
   ```
   > for i in /sys/bus/{pci/devices,platform/devices,virtio/devices,soc/devices/soc?,vmbus/devices}/*/modalias; do [[ -e $i ]] && [[ -n $(< "$i") ]]  && echo $i; done | wc -l
   79
   ```
   
   Every call to `dracut_instmods` spawns a `dracut-install` process, which in the
   previous example means calling `dracut-install` 79 times using the same
   arguments.
   
   If any call to `dracut-install` fails, dracut continues its execution (even the
   errors are not shown, because it's called with `--silent`). Therefore, let's
   take the contents of all the `modalias` files into an array and call
   `dracut-install` only once, adding also the `-o` argument, so if any of the
   modules cannot be installed, `dracut-install` does not stop.
