tools/docker/syzbot: disable background git auto detach

Git spawns detached background processes for auto-GC (gc.autoDetach) and
auto-maintenance (maintenance.auto in Git >= 2.31) during fetch/commit.

In containers, these detached processes accumulate as defunct processes
when parent processes exit without reaping them. Furthermore, if a container
is SIGKILLed during rollout or update, the background process leaves lock
files (e.g., .git/HEAD.lock) on persistent disk, breaking future jobs.

Disable gc.autoDetach so all Git operations run synchronously in
the foreground.
