Add support to run shell commands inside a checked out
ostree branch.
The way that this works is the following:
1. Determine the branch to checkout.
2. Checkout the branch in the workspace.
3. Use systemd-nspawn to create a shell inside
the branch.
Test Plan
PASSED Installed apt-ostree from git repo.
PASSED Run sudo apt-ostree compose create \
--base config/debian/bookworm \
--repo /repo debian/bookworm \
bookworm-test
PASSED Run sudo apt-ostree compose exec --repo /repo --branch
bookwork-test "cat /etc/debian_version"
