[mesa] Ensure files/directories have read permissions
As part of the io2 migration, we must ensure all directories are
explicitly *Opened* instead of using common *Connect* operations, since
the latter does not use any flags/rights. Because of this, when a
directory is connected to like a service, the connection lacks any
rights.
This only works right now as in io1, many operations - like directory
enumeration - were unprivileged. In order to start enforcing the new
io2 rights model, we need to require that callers opening directories
(or other node types) explicitly set the flags/rights they want.
