cuda: disable CUDA plugin for pre-dump

Browse Source 
Temporarily disable CUDA plugin for `criu pre-dump`.

pre-dump currently fails with the following error:

Handling VMA with the following smaps entry: 1822c000-18da5000 rw-p 00000000 00:00 0                                  [heap]

Error (criu/proc_parse.c:116): handle_device_vma plugin failed: No such file or directory
Error (criu/proc_parse.c:632): Can't handle non-regular mapping on 705693's map 200200000
Error (criu/cr-dump.c:1486): Collect mappings (pid: 705693) failed with -1

We plan to enable support for pre-dump by skipping nvidia mappings
in a separate patch.
