  1. overlay/mounts: Mount /boot and /boot/efi ro,nodev,nosuid 

    Ironically ostree has had support for a `ro` boot for a long time,
and only more recently did we land the [sysroot readonly](coreos/coreos-assembler#736).

But we never actually went and made `/boot` `ro` for FCOS, so let's
do it now.

This was actually motivated by someone wanting to "security harden" RHCOS
running through a checklist saying certain mounts should be `nodev`.
Let's add `nosuid` while we're here.
