hle: ipc_helpers: Ignore -Wclass-memaccess

Browse source 
This warning is triggered by GCC when copying into non-trivially default constructible types, as it uses the more restrictive std::is_trivial (which includes std::is_trivially_default_constructible) to determine whether memcpy is safe instead of std::is_trivially_copyable.
