This fixes #28768 because during an image build, Nix sees bad store timestamps and attempts to fix them, but can't fix them on a running system (due to being inside a builder). Since timestamps on the store are supposed to be 1 anyway, if we fix this, that fixes image building inside booted images made this way. Note that this adds quite a bit of noise to the output, because running `cptofs` under `faketime` causes a bunch of seemingly spurious error messages and my attempts to suppress them all failed. We'll fix it when `cptofs` gets a native timestamp preservation feature.
