Fix magma installation inside docker container (#1447)

Not sure, what weird version of `wget` is getting installed, but  attempt to download https://anaconda.org/pytorch/magma-cuda121/2.6.1/download/linux-64/magma-cuda121-2.6.1-1.tar.bz2 fails with:
```

  Issued certificate has expired.
To connect to anaconda.org insecurely, use `--no-check-certificate'.
```

Also, switch from NVIDIA container to a stock `centos:7` one, to make containers slimmer and fit on standard GitHub Actions runners.
