LU-8066 tests: use lod / osp tunables on servers

Before the lustre 2.4 OSD work the lov and osc code was used on
both servers and clients. With the OSD layer work we saw the new
lod and osp layers created that are server specific. To avoid
breakage symlinks were created that went from the lod / osp to
lov / osc directories in the proc tree on the server side.

It has been a very long time since that change so we can now
safely start to unwind that handling. The first step taken here
is to migrate the maloo test from using lov / osc for the server
tunables to using lod / osp instead.
