[clang-repl] Mark asan and systemz as unsupported for now.

While waiting for the bot owners it seems that this is not a major issue due
to the big endianness of the systemz platform. Instead it looks like we are not
modelling something well for enum types. Probably `va_arg` has a bug for that
platform or similar.

The asan failure seems to be a crash in asan and maybe related to the issues
we've mentioned in llvm#102858.

This patch should appease the bots that were broken by llvm#148701
