c32isgraph/c32isprint/c32ispunct tests: Avoid test failures on OmniOS

[Bruno Haible]

On Solaris 11 OmniOS, I see these test failures:

FAIL: test-c32isgraph.sh
========================

../../gltests/test-c32isgraph.c:172: assertion 'is == 0' failed
../../gltests/test-c32isgraph.sh: line 26: 20314: Abort
FAIL test-c32isgraph.sh (exit status: 1)

FAIL: test-c32isprint.sh
========================

../../gltests/test-c32isprint.c:175: assertion 'is == 0' failed
../../gltests/test-c32isprint.sh: line 26: 20332: Abort
FAIL test-c32isprint.sh (exit status: 1)

FAIL: test-c32ispunct.sh
========================

../../gltests/test-c32ispunct.c:252: assertion 'is == 0' failed
../../gltests/test-c32ispunct.sh: line 26: 20341: Abort
FAIL test-c32ispunct.sh (exit status: 1)

This patch avoids the failures.
