sys/linux: specific descriptions for vim2m (v4l2)

Add a set of descriptions to focus the fuzzing process on the V4L2 vim2m
test driver. This should be useful to test the M2M framework.

The syscalls are based on a specific file descriptor for the vim2m
device and a selection of v4l2 ioctls that operate on it. Some of the
existing v4l2 data structure definitions have been extended to allow
restricting and selecting some options in order to narrow down the
fuzzing process.

Initial support for Request API added.
