Try to get OneAPI CI working again (FEniCS#3350)

* Try to get OneAPI CI working again

* Update ET

* Mark debug with maybe_unused

* More maybe_unused

* Allow run as root\!\!\!

* Change env vars

* Try adding ssh

* Got back to MPICH

* Remove libfabric each time

* Try adding to GITHUB_ENV

* try again

* try with I_MPI_OFI_LIBRARY_INTERNAL

* revert some things not needed
