Subject: [PATCH] ci: suppress clang 6 + cxx20

Since the main branch that passed the same check 9 days ago also fails
with clang-6 and C++20 because of the same error, "undefined reference
to allocator_traits<char>::allocate". It could be a change in upstream
and since others (e.g. gcc) works well, I suppress the setting at this
moment.
