bug#61386: [PATCH] cp,mv,install: Disable sparse copy on macOS

[George Valkov]

If I revert a0803c4bad6f8e11bb05effcc42ef433f4fc3f9b, the requirement to press 
enter after PASS: tests/rm/isatty.sh is fixed.

Sometimes it might randomly hang: gdb after
PASS: tests/rm/r-4.sh
^Cmake[1]: *** Deleting file 'tests/rm/r-root.log'
^C^C^C

ps -A |grep gdb
55051 ttys020    0:00.09 gdb -nx --batch-silent -return-child-result 
--eval-command=set exec-wrapper\011\011\011\011\011                       env 
'LD_PRELOAD=:./k.so'  --eval-command=break 
'/Volumes/coreutils/coreutils-2023-02-24.d/src/remove.c:377' 
--eval-command=source bp.py --eval-command=run -rv --one-file-system dir 
--eval-command=quit rm

even though I have applied macos-gdb-hang.patch. Other times it goes past that:
r-root.sh: skipped test: internal test failure: maybe LD_PRELOAD or gdb doesn't 
work?
and eventually the tests complete.

If it hangs and I killall -9 gdb, it continues
r-root.sh: skipped test: internal test failure: maybe LD_PRELOAD or gdb doesn't 
work?
SKIP: tests/rm/r-root.sh
PASS: tests/rm/readdir-bug.sh
