This option is already enabled when building Lagom, so let's enable it for the main build too. We will no longer be surprised by Lagom Clang CI builds failing while everything compiles locally. Furthermore, the stronger `-Wsuggest-override` warning is enabled in this commit, which enforces the use of the `override` keyword in all classes, not just those which already have some methods marked as `override`. This works with both GCC and Clang.
