cachestat03 from ubuntu_ltp_syscalls failed on B-KVM

[Po-Hsu Lin]

This is a new test case added on Jul. 23
https://github.com/linux-test-project/ltp/commit/1564e8c4700c0bd4b17282f5560d6f1774798005

And we got our fork updated recently in order to cover Oracular.
So this is not a regression.

B-4.15, B-hwe-5.4 are good. It's just failing for B-KVM for now.

Test failed with:
  TBROK: Failed to open FILE '/proc/sys/vm/compact_memory' for writing: ENOENT (2)
