devtool: prevent starting git gc in backgroundHEADmaster
Devtool creates a git repository for extracted sources in a temporary directory and then moves it to a final destination after patching is done. Unfortunately devtool is not aware that some of its git operations may have caused git garbage collector to start in background. If timing is just right a repository move fails because GC is removing git objects while they are being moved. The issue was hit on Krogoth release, but the code that moves created git repository is still the same. Disable gc.autodetach to make GC run synchronously and block git until it is done.
