numfmt: should use lowercase k with --to=si option

[jfinkels]

Environment: Ubuntu 24.04, uutils main branch (git commit 2430e2a), GNU coreutils v9.6.8-fbfd88-dirty

Steps to reproduce:

numfmt --to=si 2000

What happens now: uutils numfmt uses uppercase K:

2.0K

What I expected to happen: GNU numfmt uses lowercase k:

2.0k

Notes: this is causing a test failure in GNU test file tests/misc/numfmt.pl.

Just to make sure: Is it completely decorrelatted from any LC_* and location stuff ?

Yes, the relevant tests in tests/misc/numfmt.pl don't use localization (they turn it off at the top of the file).
