check-spacing: do not kill C++-style comments

Our HACKING guide forbids these.
There's no point in exempting these from the spacing check
if their existence is against our coding style.

Note that the non-usage of these comments itself is not enforced
by syntax check, probably because of the need to implement a C parser.
