rutabaga_gfx: convert to SafeDescriptor

To be truly OS-agnostic, we need an OS-agnostic Rust wrapper over
the OS-specific handle type.  SafeDescriptor seems to be the best
option, and I hope it on crates.io in the future.

This converts virtio_gpu/rutabaga to use the SafeDescriptor handle
when practical.  minigbm still uses File in some places, since it
needs to SeekFrom(..), but minigbm is a Linux only thing anyways.

BUG=b:173630595
TEST=boot VM in 2D/3D mode
