numfmt: ensure fields don't split on nbsp

* src/numfmt.c (newline_or_blank): Explicitly ensure
we don't match NBSP as on platforms like NetBSD 10 or Solaris 11,
NBSP is considered a blank character.
This should have been part of commit v9.8-39-g8bc11f80a
Solaris 11 test failure reported by Bruno Haible.
