Update the gitlab-ci to Fedora 32

Fedora 30 is end of life, let's use the version 32 instead.

Unfortunately, we have to disable taskswitch2 in the gitlab-ci now.
It does not seem to work anymore with the latest version of gcc and/or
QEMU. We still check it in the travis-ci, though, so until somebody has
some spare time to debug this issue, it should be ok to disable it here.
