Subject: [PATCH] fix: Only alter panic handler in riscv64 target

Previously the panic handler is inserted in all targets. This would
make clippy complain about the following error:

```
error[E0152]: found duplicate lang item `panic_impl`
```

By only altering panic handler in riscv64 target, the error would now
go away
