Set Machine's BootstrapReady when there is no ConfigRef

If there is no ConfigRef but the bootstrap data secret is set by the
user (instead of a bootstrap provider), then BootstrapReady should be
true. This is the case for MachineSet, and was originally the case for
Machine since 5113f80. However, in
d93eadc this changed as a side effect
of ensuring that bootstrap config object can continue to be reconciled
after the bootstrap provider has produced the bootstrap data secret.

This change ensures that, once a bootstrap data secret exists, in the
case of a ConfigRef it can still be reconciled, while in the case there
is no ConfigRef, BootstrapReady is set.
