Fails to compile on Ubuntu 18.04

Hello, a clean git checkout is failing to build on my system. Steps to reproduce:

git clone https://github.com/redsift/redbpf.git
cd redbpf/
cargo build

Truncated error:

error: failed to run custom build command for `bpf-sys v1.1.2 (/home/josh/Projects/redbpf/bpf-sys)`

Caused by:

You'll need to check out the submodules before building:

git submodule sync
git submodule update --init

Let me know if you still have problems after that.

Hey! Thanks for the pointer. I'm getting further in the build, but this is the error:

libbpf/include/linux/types.h:6:10: fatal error: 'stdbool.h' file not found

I do have the llvm-10 and llvm-10-dev packages installed on my system if that helps

This fixed it: actions/runner-images#104 (comment) :)
