Merge rust-bitcoin/rust-bitcoin#1063: Remove duplicate `must_use` 

bea5569cd3 Remove duplicate must_use (Tobin C. Harding)

Pull request description:

  Clippy emits:

   warning: this function has an empty `#[must_use]` attribute, but returns a type already marked as `#[must_use]`

  This is because the return type of the function `legacy_encode_signing_data_to` is `EncodeSigningDataResult` which is
  already marked as `must_use`. There is no need to have `must_use` on the function also.

  ##

  Hey apoelstra, this PR is needed before any other PR can get a green CI run. The PR that introduced this warning must have had a green CI run before the 'add clippy to CI' PR merged allowing it to merge without re-running CI.
