[PATCH i-g-t] tests/intel/xe_evict: Skip test if smem less than lmem

[priyanka.dandamudi at intel.com]

From: Priyanka Dandamudi <priyanka.dandamudi at intel.com>

Currently the tests are failing with OOO memory error.
Test requires SRAM to be as big as VRAM. For example, small-cm creates
(448 / 2) BOs with a size (1 / 128) of the total VRAM size. For
simplicity ensure the SRAM size >= VRAM before running this test.
Added code to skip the test if the system memory size is less than local
memory size.

v2: Added memory size in the skip print.(kamil)
Also added reason as a comment for the skip.(Matt)
