aws.RecursiveCopy doesn't work if you use a path that is not the current working directory

[webvictim]

What happened: RecursiveCopy fails when providing a path that isn't the current working directory.

s3-upload.force:

func(){
     aws.RecursiveCopy(
          aws.Local{Path: "./build"},
          aws.S3{Bucket: "gusteleport.gravitational.io", Key: "4.1.0/"},
     ),
}

$ ls -l *.force

-rw-rw-r--. 1 gus gus  88 Oct  9 14:17 setup.force

$ ls -ld build
drwxrwxr-x. 2 gus gus 4096 Oct  9 15:03 build

What you expected to happen: RecursiveCopy should add the source path onto the filename as part of the copy.

[webvictim]

I should add that I can probably work around this by setting the source path to . as per the example and running a chdir first, but the reason I want to use the functionality like this is so I don't upload the .force files which are present in the same directory.
