When certain directories, like /tmp, get mounted over, FCOS/Linux can act in unexpected ways. Added a sanity check for a list of directories think might be impacted by this. Also, moved the volume parsing earlier in the init process so we can catch problems before the expensive decompression of machine images. The following destinations are forbidden for volumes: `/bin`, `/boot`, `/dev`, `/etc`, `/home`, `/proc`, `/root`, `/run`, `/sbin`, `/sys`, `/tmp`, `/usr`, and `/var`.
