univ-init: set default to -Wno-universal-initializer
'{ 0 }' is the standard idiom for the universal zero initializer '{ }'.
But if the '0' is taken literally, warnings can be issued, for exemple
for 'using 0 as NULL pointer' or for 'using a positional initializer'
when the attribute 'designated_init' is used.
These warnings were not intended to be issued for this initializer
and are confusing and annoying when people have to use or want to
use standard code or ignore that '{ }' is fine to use with GCC,
clang or Sparse.
So, set sparse default to -Wno-universal-initializer, suppressing
any warnings caused by using '{ 0 }' instead of '{ }'.
