Merge rust-bitcoin/rust-secp256k1#397: Fix example dependency list 

3c9dd2fb32 Fix example dependency list (Tobin Harding)

Pull request description:

  Example relies on `rand-std` not plain `rand` dependency.

  I do not understand why the following command passes without this patch
  applied

  ```
  cargo test --no-default-features --features=std,rand,bitcoin_hashes
  ```

  But if we put the same code in a standalone binary it fails as expected?

  Since the running of this test is _unusual_ and it is primarily meant as
  an entry point example to the library, remove the mention of "alloc"
  feature and just depend upon "std".

  Fixes: #395
