freerdp2: Fail to build against OpenSSL 3.0

[Simon Chopin]

Hello,

As part of a rebuild against OpenSSL3, this package failed to build on one or
several architectures. You can find the details of the rebuild at

https://people.canonical.com/~schopin/rebuilds/openssl-3.0.0-impish.html

or for the amd64 failed build, directly at

https://launchpad.net/~schopin/+archive/ubuntu/openssl-3.0.0/+build/22098535/+files/buildlog_ubuntu-impish-amd64.freerdp2_2.3.0+dfsg1-2.0~ssl3ppa1.1_BUILDING.txt.gz

We're planning to transition to OpenSSL 3.0 for the 22.04 release, and consider
this issue as blocking for this transition.

You can find general migration informations at
https://www.openssl.org/docs/manmaster/man7/migration_guide.html
For your tests, you can build against libssl-dev as found in the PPA
schopin/openssl-3.0.0

Looking at the logs, I cannot figure out why the build failed ? There are no warnings,
no errors, but the linking stage just failed silently.

Minimalistic patch to get things building by backporting patches from the latest upstream release.
