As the current AArch64 integration test builds kernel every time,
which would take unnecessary time in CI and therefore not ideal.
This commit refactors the AArch64 kernel building strategy to:
1. Keep the Linux kernel source code directory instead of deleting
it everytime after the kernel is built.
2. In integration test script, check if the Linux kernel source
code directory exists. If so use `git fetch && git checkout -f` to
keep the source code always updated, else run `git clone` to get
the source code.
3. Copy config file in and then compile the kernel.

It gets bubbled all the way up from hypervsior crate to top-level
Cargo.toml.
Cloud Hypervisor can't function without KVM at this point, so make it
a default feature.
Fix all scripts that use --no-default-features.

This commit adds supporting components and code for enabling the
AArch64 integration tests, including:
1. A Linux kernel config file to build kernel on AArch64 machines.
2. Refactoring the `run_integration_test.sh` to architecture
specific scripts for readability.
