It seems that the intention was to format a number in base 8 (as
suggested by the %o format specifier), but `perms` is a `std::string`
and not a number. Looks like `rawMode` is the correct thing to use here.

In the common case, nix develop is running against a dirty checkout of a project.
This patch removes the warning about a dirty tree on nix develop only.
Close FH-736
This name is close to the Nixpkgs lib function `escapeShellArg`,
making it easier to find.
A friendlier function with the same behavior as lib could be added
later.

Assuming this check was left over from the time `drv` could be a
`BasicDerivation`.
I split it out before to try to separate the building logic, but now we
have the much better `DerivationBuilder` abstraction for that. With that
change, I think `LocalDerivationGoal` has outlived its usefulness.
We just inline it back into `DerivationGoal`, and do so with minimal
`#ifdef` for Windows.
Note that the order of statements in `~DerivationGoal` is different than
it was after the `~LocalDerivationGoal` split, but it is *restored* to
the way it original was before --- evidently I did the split slightly
wrong, but nobody noticed, probably because the order doesn't actually
matter.

Now that `DerivationBuilder` is created after the underlying data has
already been initialized, we can just refer this data normally, with a
direct reference.
Only `parsedDrv` takes a (borrowing) pointer, because independent of
initialization the derivation may or may not have structured attrs.
This is needed to devirtualize them when they get passed to a
derivation or builtins.toFile. Arguably, since this builtin is unsafe,
we could just ignore this, but we may as well do the correct thing.
The building logic is now free of the scheduling logic!
(The interface between them is just what is in the new header. This
makes it much easier to audit, and shrink over time.)
We have a new `DerivationBuilder` struct, and `DerivationBuilderParams`
`DerivationBuilderCallbacks` supporting it.
`LocalDerivationGoal` doesn't subclass any of these, so we are ready to
now move them out to a new file!
