Error running `podman build` with option `--build-context` on Hyper-V

Issue Description

An image's build fails on Hyper-V when using additional build context. The same build works fine when using WSL as the machine provider.

copier: get: "/test": getting extended attributes for "/test": listing extended attributes of "/test": invalid argument

⚠️This error will be reproducible after we merge these PRs (1 and 2). Currently, podman build fails earlier with a different error message. ⚠️One way to address this problem would be to send the additional build contexts as tarfiles. However, investigating the root cause of this problem is still important as it can have other effects.

Steps to reproduce the issue

Create a folder context1 and add an empty file test in it

Create a folder context2 and add this Dockerfile:

FROM quay.io/libpod/alpine_nginx
COPY --from=test-context test /"

Run podman build --build-context test-context=.\context1 .\context2
