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.
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.

... by moving our stuff out of the way from upstream's
`nixComponents` and `nixDependencies` attrsets.
(I prefer not to use overlays, but let's make it work this way
first)
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.
While it seems unlikely that `$USER` will be unset while `$HOME` is set,
as `$USER` is not used in the script and as `nix-profile-daemon.fish` is
not checking `$USER`, it seems better to remove this check.
`nix-profile.fish` and `nix-profile-daemon.fish` now become identical.
It seems reasonable to add both `$HOME/.profile/bin` and
`@localstatedir@/nix/profiles/default/bin` to `$PATH` for both user
local and daemon based nix execution. Nix daemon execution mode does
not affect these path.
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.)
