Subject: [PATCH 1/2] tests: fix FP in ls/stat-free-color.sh

On newer systems like Fedora 34 and openSUSE Tumbleweed, ls(1) calls
newfstatat(STDOUT_FILENO, ...), but only when there is something to
output.

* tests/ls/stat-free-color.sh: Add -a option to the reference invocation
of ls, thus enforcing something gets output.

Subject: [PATCH 2/2] tests: fix tests/cp/sparse-2.sh false failure on some
 systems

* tests/cp/sparse-2.sh: Double check cp --sparse=always,
with dd conv=sparse, in the case where the former didn't
create a sparse file.  Now that this test is being newly run
on macos, we're seeing a failure due to seek() not creating
holes on apfs unless the size is >= 16MiB.
