[PATCH v2] 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 current test fails
on new kernel as the output is mismatch to the goldens. In order to make
the current golden output works for both old and new kernels, this patch
filter the new error message out to match the olds.

V2: make the filter as a local function as per Dave's comments
