This reverts commit 60d064d3fd.
The logged test failure was because of missing memory controller in
testing cgroup. With the test fixed in previous commit, memory
attributes are delegated as expected.
Ref: #32439
Having these named differently than the test itself mostly creates
unecessary confusion and makes writing logic against the tests harder
so let's rename the testsuite-xx units and scripts to just use the
test name itself.
