Merge #16669: build: use new fork of osslsigncode for windows gitian signing

feb5075777 build: use osslsigncode 2.0 in gitian (fanquake)

Pull request description:

  The original osslsigncode project, https://sourceforge.net/projects/osslsigncode, has been marked as abandonware:
  > This is now - and has been for a long while - abandonware. Feel free to create your own forks etc.".

  However, a fork has emerged, https://github.com/mtrojnar/osslsigncode, that has incorporated
  theuni's patches ([add the -pem option in extract-signature mode ](36715c1183) & [add the attach-signature command](3be7eb1676)) as well as updated the tool to work with OpenSSL 1.1 and other improvements.

  This commit switches the windows signer descriptor to use this new version of `osslsigncode`.

  I've tested using this new version of `osslsigncode` while doing a 0.18.1 gitian build, and it "seems" to work. However this needs a look over from Cory, to check if the tool is still compatible with his usage in the [`detached-sig-create.sh`](https://github.com/bitcoin/bitcoin/blob/master/contrib/windeploy/detached-sig-create.sh) script, as well as some review of the changes to `osslsigncode` itself. Hence WIP and chasing Concept ACKs / NACKs.
