[PATCH v3] xfstests: shared/051: add filter to match the golden output for large acls

[Jeff Liu]

From: Jie Liu <jeff.liu at oracle.com>

On old kernel we return EINVAL if hit the limits of maximum number of
ACLs but return E2BIG on new kernel, which cause the test failes on new
kernel as the output is mismatch to the goldens. This patch fix it by
updating the golden output with the new error message and replacing the
old error message with it via a filter.

V3->V2: filter out the old error message to the new and update golden output to match it
V2->V1: filter out the new error message to the old
