vagrant: fix lack of asm/types.h on Ubuntu images

[geyslan]

This adds missing includes as running the test in a vagrant vm was having errors like:

selftests: do not depend on uapi headers

- include missing types in vmlinux.h
- fix headers for all bpf.c files

And removing multilib from build dependencies as well:

#321

Closing this as not needed.
