c: add a workaround for SQLITE_TRANSIENT being mistranslated
See https://github.com/ziglang/zig/issues/15893
zig's translate-c creates an invalid type for SQLITE_TRANSIENT on some
architectures (aarch64, riscv64 and others).
We can work around this by making a C function that returns -1 cast to
the proper destructor type and use that from zig (thanks
https://github.com/Cloudef for mentioning this in this comment: https://github.com/ziglang/zig/issues/15893#issuecomment-1925092582)
