papatcher can run out of cache space sometimes

[RustyRaptor]

I made an issue on the patcher github already but I am making one here because the main purpose is so that if anyone else runs into this they can find this. planetary-annihilation/papatcher#2 (comment)

Here's what I did.

1. Create a fork of the papatcher and a fork of this docker github repo.
2. In the docker fork inside the Dockerfile change it so that it points to your version of the papatcher.go instead of the original.
3. In the fork of the papatcher you need to find where it constructs the path to the cache directory. In the one for linux change the "~" to be a hard coded path to your home. For example "/home/username"
4. Now once you did all that you can run the same docker build command but of course replace the github repo to the new repo you made for the docker file.

And because why not. This isn't related to this specific docker but if you had this issue you probably also have the issue of docker storing everything in /var/lib/docker/overlay2
well here's the solution to that one. https://forums.docker.com/t/how-to-change-var-lib-docker-directory-with-overlay2/43620/2

Thanks for pointing this out :)

I've marked as wontfix since this is an upstream issue, but I invite you to close this if that problem is resolved in the patcher
