gitlab-ci: Remove the second superfluous macos task

While there might have been bigger differnces between the -base and
the -xcode images in the beginning, they almost vanished in the
current builds, e.g. when comparing the output of the "configure"
step after cleaning up the differences due to temporary path names,
I only get:

Since we're not using Xcode itself at all, it seems like it does not
make much sense anymore to waste compute cycles with two images here.
Thus let's delete the -xcode job now.

[AJB: fix up commit formatting which trips up b4]
