The broken pipe error is not handled in the case of the round robin
strategy (typically used with --filter).
Align to the other strategies to silence that error in that use case
too.

Implement distributing lines of a file in a round-robin manner to a
specified number of chunks. For example,
$ (seq 1 10 | split -n r/3) && head -v xa[abc]
==> xaa <==

7
10
==> xab <==

While the rust coreutils semantics were arguably more correct,
they were different than the gnu split semantics when handling a
file without a trailing EOF. This patch addresses that difference
and allows passing one more GNU test suite.
* Fix a bug in split where chunking would be skipped when the chunk size
happened to be an exact divisor of the buffer size used to read the
input stream.
The issue here was that file was being split byte-wise in chunks of 1G.
The input stream was being read in chunks of 8KB, which evenly divides
the chunk size. Because the check to allocate the next output chunk was
done at the bottom of the loop previously, it would never occur because
the current input chunk was fully consumed at that point. By moving the
check to the top of the loop (but still late enough that we know we have
bytes to write) we resolve this issue.
This scenario is unfortunately hard to write a test for, since we don't
explicitly control the input chunk size.

Fix a bug in the behavior of `split -e -n NUM` when the input file is
empty. Previously, it would panic due to overflow when subtracting 1
from 0. After this change, it will terminate successfully and produce
no output chunks.
