Since 3a251bac0d1a (trace2: only include "fsync" events if we git_fsync(),
2022-07-18), the FreeBSD builds are failing in t5351.6. See
https://cirrus-ci.com/task/4577761405698048 for an example. The run at
https://cirrus-ci.com/task/6004115347079168 shows that this patch fixes the
bug.

While verifying the fix on Windows, I noticed a recent, rather terrible
performance regression: t5351 all of a sudden takes almost half an hour
[https://github.com/git/git/runs/7398490747?check_suite_focus=true#step:5:171]
to run on Windows. I found a fix, and it now passes in less than half a
minute
[https://github.com/gitgitgadget/git/runs/7578071365?check_suite_focus=true#step:5:125]
again.

Johannes Schindelin (2):
  t5351: avoid relying on `core.fsyncMethod = batch` to be supported
  t5351: avoid using `test_cmp` for binary data
