SWDEV-501675 - disable Unit_hipMalloc_AllocateMoreThanTotalRAM (#63)

Unit_hipMalloc_AllocateMoreThanTotalRAM is an invalid test. hipMalloc is able to allocate more than RAM size if VRam is larger, unless the test is meant to only allocate on host device.
Previously this test may have passed because of an incorrect check on hipMalloc limit: we had incorrectly limited allocation to physical ram size. This is no longer correct. We could always allocate Vram limit or sometimes system ram limit if Vram is full, fixed in https://github.com/AMD-ROCm-Internal/clr/pull/122
