Add checkpoint sync flag for TD superblock writes.

Writes to the TD filesystem must not be committed while an uncommitted
checkpoint is pending for userdata. Adds a flag to TD superblock write
messages telling storageproxyd to not perform the write until it is safe
to do so.

Test: Boot with userdata checkpointed and attempt a TD write
