GG. uefi v0.4.4 needs new nightly and breaks the build.

Try to update rboot submodule.

The device file system framework still need to be refactored, maybe next time. It's hard to add a custom device file and associate device resources to different processes.

Another issue: Rust nightly 2020-03-23 lacks rustfmt component and it has not been fixed until now. So we should update nightly again once rustfmt is back.
