Add tools to run bindgen

[vireshk]

The containers used for builds currently don't have necessary tools to compile bindgen stuff, which compiles few C files and create rust bindings.

The tools required are:

• libclang-dev
• clang
• musl-tools

We also need to configure the container to pass the include path, to the Linux libraries, for the musl build, else we get more errors like "const.h" not found.

This pull request should build from the container if this works fine:

rust-vmm/vhost-device#68
