daemon: Add “git-download” built-in builder.
The new builder makes it possible to break cycles that occurs when the fixed-output derivation for the source of a dependency of ‘git’ would itself depend on ‘git’. * guix/scripts/perform-download.scm (perform-git-download): New procedure. (perform-download): Move fixed-output derivation check to… (guix-perform-download): … here. Invoke ‘perform-download’ or ‘perform-git-download’ depending on what ‘derivation-builder’ returns. * nix/libstore/builtins.cc (builtins): Add “git-download”. * tests/derivations.scm ("built-in-builders"): Update. ("'git-download' built-in builder") ("'git-download' built-in builder, invalid hash") ("'git-download' built-in builder, invalid commit") ("'git-download' built-in builder, not found"): New tests.
