Fix build when current user's UID is not 1000

By default, yq user created in Docker image will have UID 1000.
However, the mounted volume will keep their existing UID:GID
inside the container, and will cause permissoin error when they
don't belong to the same UID:GID that yq belong to.

This commit fixes yq's permission before building.
