build: Enable -Wnull-dereference warning

Browse Source 
This enables `NULL` pointer dereference checking in the compiler. This
isn’t as good as static analysis, but it should hopefully catch some
simple errors without too high a false positive rate.

If the false positive rate is too high to be useful, we can always
disable it again.
