Cleanup: reinstate override modifiers

This reverts commit 1c4a859c8d0b37b2e938209fe9c4d99e9758327a,
where the override modifiers were removed owing to the noisy
"inconsistent override modifiers" which is default-on in clang.

This warning was disabled in 77577f717f5aad38ea8c4c41c10c181486c4337f,
so we can reinstate the overrides.
