This does what we already do for the LUKS backend: instead of mounting the source directory directly to the final home dir, we instead bind mount it to /run/systemd/user-home-mount (where /run/ is unshared and specific to our own mount namespace), then adjust its mount flags and then bind mount it in a single atomic operation into the final destination, fully set up. This doesn't improve much on its own, but it makes things a tiny bit more correct: this way MS_NODEV/MS_NOEXEC/MS_NOSUID will already be applied when the bind mount appears in the host mount namespace, instead of being adjusted after the fact. Doing things this way also makes things work more like the LUKS backend, reducing surprises. Most importantly it's preparation for doing uidmapping for directory homes, added in a later commit.
