configure: Make -Waddress-of-packed-member warnings be errors 

We have now managed to eradicate all the places in the codebase
that triggered clang's -Waddress-of-packed-member warning. Remove
the compiler flag that exempted it from our usual -Werror policy.
This will prevent any new problematic code being added in future.
