Get rid of Finally in DerivationBuilderImpl::unprepareBuild

Browse source 
Calling `reset` on this `std::optional` field of `DerivationBuilderImpl`
is also what the (automatically created) destructor of
`DerivationBuilderImpl` will do. We should be making sure that the
derivation builder is cleaned up by the goal anyways, and if we do that,
then this `Finally` is no longer needed.
