[i-g-t v2] tests/intel/xe_madvise: Skip purge tests under low RAM

[i-g-t v2] tests/intel/xe_madvise: Skip purge tests under low RAM

[Arvind Yadav]

The purge tests create memory pressure to trigger BO eviction. If the
system is already low on RAM, this extra pressure can push the machine
into OOM and kill the test before it can clean up.

Check available RAM before starting the pressure allocation and skip when
there is not enough memory.

v2:
  - Drop unrelated chunk/max_t() changes. (Kamil)
  - Keep the original overpressure calculation. (Kamil)
