Rewrite 3 very similar run-make alloc tests to rmake

[Oneirical]

Part of #121876

#121918 attempted to port these 3 tests 2 months ago. However, since then, the structure of run-make-support has changed a bit and new helper functions were added. Since there has been no activity on the PR, they are good low-hanging fruit to knock down, using the new functions of the current library.

There is also the removal of a useless import on a very similar test.
