[roll] Roll fuchsia [fxfs] Extend read locks for open to get vmo.

This ensures that a blob cannot be modified (impossible previous to the
change that supports overwriting) after open but before the child vmo is
created.

Simplifies downgrading from OpenedNode as well and updates comment on
lookup_blob to remove the warning that no longer applies since purge has
been moved to drop instead of final close.
