compilers/detect: remove unsupported -cpp flag for Clang preprocessor detection
Clang's resource files, e.g. /usr/share/clang/clang++.cfg, can be used to bump the default standard level across the system.
However due to llvm/llvm-project#61641 `clang++ -std=c++17 -E -dM -` doesn't work. The workaround is to pass the language explicitly.
4ad792e158b6059eb847dd0562aff9bd7029981f fixed the issue by passing the language explicitly, but started passing the `-cpp` flag, which Clang doesn't support.
Basically Clang would always fallback to the second detection attempt as a result. Remove the unsupported flag and the above scenarios works now too. 🙂
