gitlab-ci: drop workaround for Python certificate store on Windows

On Windows, we have been running into some issues in the past where the
certificate store for Python is broken on the GitLab CI runners using
Windows. The consequence was that we weren't able to establish any SSL
connections via Python, but we need that feature so that we can download
the Meson wraps. The workaround we employed was to import certificates
from the cURL project into the certificate store via OpenSSL.

This is obviously an ugly workaround. But even more importantly, this
workaround fails every time Chocolatey updates its OpenSSL packages. The
problem here is that the old OpenSSL package installer will be removed
immediately once the newer version was published, But the Chocolatey
community repository may not yet have propagated the new version of this
package to all of its caches. The result is that for a couple hours (or
sometimes even one or two days) we always fail to install OpenSSL until
the new version was propagated.

Luckily though, it turns out that the workaround doesn't seem to be
required anymore. Drop it to work around the intermittent failures and
to clean up some now-unneeded legacy cruft.
