            fix(git-lfs): run git maintenance synchronously during %check to stop flaky t-prune.sh

Git 2.54 switched the post-commit `git maintenance run --auto` job to the 'geometric' strategy, dropping the repack trigger from 6700 to ~100 loose objects. t-prune.sh commits 1000 files then runs `git lfs prune`, so the detached background repack races prune and intermittently fails with 'missing object'.

Set maintenance.autoDetach=false for the test suite so the post-commit repack runs in the foreground and finishes before prune, closing the race while keeping the maintenance path exercised. Mirrors git's own test-suite fix for the same geometric-strategy race (git.git 09505b1). Scoped to the throwaway test repos; the shipped binary is unchanged.

Reported upstream: git-lfs/git-lfs#6309

Resolves: rhbz#2503921
