On systems where running t7704.09 takes longer than 10 seconds, the test can fail.

The test works by doing the following:

 - First write three unreachable objects, backdating the mtime for a
   single object ($foo) which we expect to prune.

 - Repack the repository into a pack containing reachable objects, and
   another three cruft packs, each containing one of the objects
   written in the previous step.

 - Backdate the mtimes of the cruft pack *.mtimes files themselves.
   (Note that this does not affect what is pruned further down in the
   test, but is done to ensure that the cruft packs are rewritten
   during that step).

 - Then repack with --cruft-expiration=10.seconds.ago, expecting to
   prune one of the three unreachable objects written in the first
   step.

 - Assert that the surviving cruft packs were rewritten, object $foo is
   pruned, and unreachable objects $bar, and $baz remain in the
   repository.

If longer than 10 seconds pass between writing the three unreachable objects (the
first step) and the "git repack --cruft" (the fourth step), we will mistakenly prune
more objects than expected, causing the test to fail.

The $foo object which we expect to prune has its mtime set back to
10,000 seconds relative to the current time, but we prune it with a cutoff of
10.seconds.ago.

Instead, set the cutoff to be 1,000 seconds to give the test much longer time to run
without failing. This helps platforms where running individual tests can perform
slowly, on my machine this test runs much more quickly:

   $ hyperfine './t7704-repack-cruft.sh --run=9'
   Benchmark 1: ./t7704-repack-cruft.sh --run=9
     Time (mean ± σ):     647.4 ms ±  30.7 ms    [User: 528.5 ms, System: 124.1 ms]
     Range (min … max):   594.1 ms … 696.5 ms    10 runs
