Extract imports from "bpf2go.hfiles.go" in the output dir, scan packages
for header files, and expose headers to clang. C code consumes headers
by providing a go package path in include directive, e.g.
bpf2go.hfiles.go:
package awesome
import (
_ "example.org/foo"
)
frob.c:
#include "example.org/foo/foo.h"
It is handy for sharing code between multiple ebpf blobs withing a
project. Even better, it enables sharing ebpf code between multiple
projects using go modules as delivery vehicle.
By listing build dependencies in a .go file, we ensure that they are
properly reflected in go.mod.
