Latest vndr picks up lots more stuff (due to .c file inclusion)

[ijc]

Rerunning vndr on containerd with the latest version picked up a lot of extra stuff, I think because of #69/#70. Is this expected or is it going further than was intended?

See containerd/containerd@623407a which has stat of:

Seems this change is to accommodate a case where someone was directly including a .c file from a directory with no .h file using cgo. See https://github.com/leslie-wang/go-mediainfo/blob/master/mediainfo/mediainfo.go#L7.

While including more unused stuff is not ideal, since cgo supports this case vndr should as well. Parsing the cgo includes would be too ugly :)

Ah yes, I forgot that the cgo stuff would be opaque to the Go AST.
