AnishMulay 54218f10df selftests/mm: skip migration tests if NUMA is unavailable ...

Currently, the migration test asserts that numa_available() returns 0.  On
systems where NUMA is not available (returning -1), such as certain ARM64
configurations or single-node systems, this assertion fails and crashes
the test.

Update the test to check the return value of numa_available().  If it is
less than 0, skip the test gracefully instead of failing.

This aligns the behavior with other MM selftests (like rmap) that skip
when NUMA support is missing.
