[oe] [meta-clang][PATCH] Turn off wchar in editline for native*

[Jeremy Puhlman]

| /build/poky/build/tmp/work-shared/llvm-project-source-9.0.0-r0/git/lldb/include/lldb/Host/Editline.h:36:19:
| fatal error: codecvt: No such file or directory
|  #include <codecvt>
|                    ^

wchar causes codecvt to be included, which does not exist on centos7, which
prevents clang-native from building.
