Configurable user IDs

[etcwilde]

When working with these containers to debug issues locally, it's sometimes useful to have the source directory live on the host, while building in the container. In order for permissions to line up, the user ID numbers need to match or the build-user may not be able to create the necessary directories.

This patch allows setting the build-user user ID so that the permissions line up and the user in the container and host can manipulate the files.

Override the build user ID with the current user's ID is done with the following command to ensure that the permissions on any volumes are kept in sync is the following:
docker build --build-arg BUILD_USER_ID=$(id -u) ...

@swift-ci please test

I'm going to need more output than [FAILED] - swift-ci/main/ubuntu/24.04/Dockerfile.
I am unable to reproduce a failure with this Dockerfile locally.

Static SDK

ERROR: failed to solve: failed to compute cache key: failed to calculate checksum of ref c134ce27-11c9-4288-a10a-13dadbadd510::xc4kljypnmeqd83a464gmh764: "/resources": not found

Most of these look like either the distro is EOL or an infra issue. I can avoid the EOL distros. I'm not sure what is happening with the static SDK though. Will see if I can reproduce that. This change shouldn't have an effect.

[etcwilde]

Ah, ci_test.py is trying to build the static SDK from a different directory than the directory that the Dockerfile is in, which doesn't work because the Dockerfile copies in the resources directory, which is situated next to the Dockerfile.

Running: docker build --no-cache=true -f swift-ci/sdks/static-linux/Dockerfile .
