class tests: re-enable a bunch of tests

Many of these tests were failing due to opal_init() failing in some
cases (because the opal shmem framework needs installed components, so
"make distcheck" would fail these tests because the opal shmem
components were not installed).  However, all of these tests seem to
be fine with opal_init_util() -- so let's re-enable these tests.
