c32isblank tests: Avoid test failure on NetBSD 10.0

[Bruno Haible]

In a testdir of module 'c32isblank' without module 'uchar-c23', I see a
failure:

FAIL: test-c32isblank.sh
========================

test-c32isblank.c:107: assertion 'is == 0' failed
[1]   Abort trap (core dumped) LC_ALL=${LOCALE_FR_UTF8} ${CHECKER} ./test-c32...
FAIL test-c32isblank.sh (exit status: 1)

The cause is that here, iswblank (L'\f') returns true, not false (as expected).

This patch avoids the failure.

        c32isblank tests: Avoid test failure on NetBSD 10.0.
        * tests/test-c32isblank.c (main): Disable test of '\f', that fails in
        the fr_FR.UTF-8 locale.
