PR82322: S/390: Fix vec_ceil and friends

vec_ceil and friends are expanded by vecintrin.h to __builtin_s390_vfi
which is an overloaded builtin being replaced by either
__builtin_s390_vfisb or __builtin_s390_vfidb depending on its argument
types.

The problem in this PR was that the overloaded builtin definition of
__builtin_s390_vfi was missing in s390-builtins.def.
