Containerfile for building PCSX2

pcsx2.dockerfile

# Containerfile (aka Dockerfile) with all deps for building PCSX2
#
# `docker build -f Containerfile -t pcsx2-builder`
# `docker run -v .:/build:Z pcsx2-builder bash -c './build.sh --clean --release --lto -DQT_BUILD=TRUE'`
#
# Using podman instead of docker is fine too just make sure to `podman unshare chown 1001:1001 /path/to/pcsx2src` before running
# and `podman unshare chown -R 0:0 /path/to/pcsx2src` after.
