gitian-win-signer.yml steps fail to compile osslsigncode-1.7.1

[underdarkskies]

osslsigncode-1.7.1 fails to compile under bionic(does not support openssl 1.1.1) unless you downgrade to xenial versions manually :
openssl_1.0.2g-1ubuntu4.13_amd64.deb
libssl1.0.0_1.0.2g-1ubuntu4.13_amd64.deb
zlib1g_1.2.8.dfsg-2ubuntu4.1_amd64.deb
zlib1g-dev_1.2.8.dfsg-2ubuntu4.1_amd64.deb
libssl-dev_1.0.2g-1ubuntu4.13_amd64.deb

just to add: the documentation in release-process.md is a bit fuzzy, as the detached-sig-create.sh uses the -t switch
yet the version of osslsigncode compiled from gitian-win-signer is configured --without-curl
a necessary prereq(curl) to be able to execute the -t switch
