Subject: [PATCH] Switch back to using OpenBLAS for Ubuntu 22

Ubuntu 20 builds were switched to the default reference BLAS because
of a bug with the OpenBLAS package. That bug does not seem to affect
Ubuntu 22, so switch back to using OpenBLAS for Ubuntu 22, for
consistency with all other R builds.
