We are still too close to the limit of 1 hour (at least with the 2019
image and the 2022 image is about the same), so reduce the build time by
not building libimcv natively, which saves about 10 minutes.
Also, only build against OpenSSL 1.0.2 (on the 2017 image) and 1.1.1 (on
the 2019 image) as these are the only versions for which OpenSSL provides
extended support.
In particular with the 2019 image, the time required often exceeded the
maximum of 60 minutes. Using lld reduces the runtime quite a bit (it's
still close to the limit, though).
This doesn't work with the old OpenSSL version we use with the 2015
image (that libeay32.lib file just doesn't seem to work), so continue
to use ld (the build on that image is the quickest anyway).
On the recently updated 2019 image, autoreconf is not found anymore, as
recent versions of msys2 don't ship autools with base-devel aymore, so
install the autotools package explicitly.
For some reason, setting the time zone via TZ to `GST-1GDT` in the utils test
doesn't work anymore (the DST zone is not considered, it's as if only `GST-1`
was configured).
