Workaround criu re-linking output in system test

When run on an F36 host using netavark/aardvark-dns, for whatever
underlying reason most checkpoint/restore tests are emitting an error
similar to:

`criu: Symbol `__rseq_offset' has different size in shared object,
consider re-linking`

This extraneous output is causing the basic checkpoint system test to
fail.  Since, all other testing of checkpoint/restore feature is
passing (also with the extraneous message) loosen the system test
sensitivity to match.
