Subject: [PATCH] vm-allocator: Enable build with kvm feature

Currently `vm-allocator` module cannot be solely built, by add
`features` section and specifying `arch/kvm` to turn on the features
required for its dependency - `arch` module to build. Thus enabling
`vm-allocator` crate to be built and tested with command:

```sh
cargo build -p vm-allocator --features kvm
```
