tests/dd/skip-seek-past-file.sh fails on macOS 15 when checking for a
warning being printed when seeking past the max file size [1].

Reproducing outside the test suite:

$ > file
$ dd bs=1 skip=9223372036854775807 count=0 status=noxfer < file
0+0 records in
0+0 records out
$ echo $?
0

Note that if the input is a non-empty file the expected warning _is_ printed:

$ echo > file
$ dd bs=1 skip=9223372036854775807 count=0 status=noxfer < file
dd: 'standard input': cannot skip to specified offset
0+0 records in
0+0 records out
$ echo $?
0

Thanks, I installed the attached patch a couple of days after your bug 
report, but unfortunately forgot to reply to your email until now. This 
patch appears in coreutils 9.6.
