  Fix char8_t in C mode regression from fb65b179

When doing that NFC refactor, I'd messed up how char8_t was reported,
which resulted in it being considered a 'future' keyword, without the
corresponding diagnostic, which lead to an assert.  This patch corrects
the char8_t to ONLY be future in C++ mode.
