[Libomptarget] Stop testing CPU offloading with LTO

Summary:
Some of the buildbots don't find the libraries because they don't build
for the GPU. Although it should always be there it's unclear why these
buildbots are having problemsd. LTO is only interesting on the GPU and
these tests take extra time anyway so I'm just going to disable them for
now.
