stdio: Suppress %Z format for clang
clang does not handle %Z on print, and just suppressing
-Wformat-invalid-specifier might trigger another warning for extra
arguments (since %Z is ignored). So suppress -Wformat-extra-args
as well.
For tst-fphex.c a heavy hammer is used since the printf is more
complex and clang throws a more generic warning.
