Adapt to C++20 deleted ostream << for sal_Unicode* (aka char16_t*)

<http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1423r3.html> "char8_t
backward compatibility remediation", as implemented now by <https://gcc.gnu.org/
git/?p=gcc.git;a=commit;h=0c5b35933e5b150df0ab487efb2f11ef5685f713> "libstdc++:
P1423R3 char8_t remediation (2/4)" for -std=c++2a, deletes operator << overloads
that would print a pointer rather than a (presumably expected) string.

But here it should be fine to print pointers, esp. as there are null pointers
involved.
