Relax workaround for d_uselocale from RT #128867.

More precisely, tailor the application of the workaround to the FreeBSD
userland version ranges specified in
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211743#c10.  (Using
userland version ('uname -U') rather than kernel version ('uname -K') at
suggestion of Mathieu Arnold.

We probably don't need an 'else' branch; let Configure handle it.
