univ-init: conditionally accept { 0 } without warnings
In standard C '{ 0 }' is valid to initialize any compound object.
OTOH, Sparse allows '{ }' for the same purpose but:
1) '{ }' is not standard
2) Sparse warns when using '0' to initialize pointers.
Some projects (git) legitimately like to be able to use the
standard '{ 0 }' without the null-pointer warnings
So, add a new warning flag (-Wno-universal-initializer) to
handle '{ 0 }' as '{ }', suppressing the warnings.
