rust: init: disable doctests

The build system cannot handle doctests in the kernel crate in files
outside of `rust/kernel/`. Subsequent commits will move files out of
that directory, but will still compile them as part of the kernel crate.
Thus ignore all doctests in the to-be-moved files.

Leave tests disabled until they are separated into their own crate and
they stop causing breakage.
