  [DSE] Remove `uninitialized` from `allockind` when creating dummy zeroed variant function (#149336)

cc https://github.com/llvm/llvm-project/pull/138299

rustc sets `allockind("uninitialized")` - if we copy the attributes
as-is when creating a dummy function, Verify complains about
`allockind("uninitialized,zeroed")` conflicting, so we need to clear the
flag.
