Arne Welzel 247931f2df logging/Manager: Non-null strings for empty strings 
After #4724, empty strings would result in nullptrs being stored in the
threading::Value's string_val.data field instead of a valid pointer to
an empty strings. This upsets UBSAN's  nonnull check for memcpy()

    [01:29:45.807]   ../../src/SerializationFormat.cc:80:33: runtime error: null pointer passed as argument 2, which is declared to never be null
    [01:29:45.807]   /usr/include/string.h:44:28: note: nonnull attribute specified here
    [01:29:45.807]       #0 0x5b2e9c933a3f in zeek::detail::SerializationFormat::WriteData(void const*, unsigned long) /zeek/build/src/../../src/SerializationFormat.cc:80:5
    [01:29:45.807]       #1 0x5b2e9c935184 in zeek::detail::BinarySerializationFormat::Write(char const*, int, char const*) /zeek/build/src/../../src/SerializationFormat.cc:371:40

Continue to allocate the empty string for now as a fix.
