pallet revive: rpc build script should not panic

[ggwpez]

This can error when you use cargo remote and probably also with cargo vendor.
Still seeing two more build errors, but at least this one is fixed.

Other one:

error: set `DATABASE_URL` to use query macros online, or run `cargo sqlx prepare` to update the query cache
   --> substrate/frame/revive/rpc/src/receipt_provider/db.rs:123:17
    |
123 |               let result = query!(
    |  __________________________^
124 | |                 r#"
125 | |                 INSERT OR REPLACE INTO transaction_hashes (transaction_hash, block_hash, transaction_index)
126 | |                 VALUES ($1, $2, $3)
...   |
130 | |                 transaction_index
131 | |             )

and (maybe Rust version related, this is 1.84.1)

error[E0282]: type annotations needed
   --> substrate/frame/revive/rpc/src/receipt_provider/db.rs:102:34
    |
102 |         let (tx_result, logs_result) = tokio::join!(delete_transaction_hashes, delete_logs);
    |                                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ cannot infer type
    |
    = note: this error originates in the macro `$crate::join` which comes from the expansion of the macro `tokio::join` (in Nightly builds, run with -Z macro-backtrace for more info)
