[PATCH] generic/245: Filter mv error message

[Su Yue <glass.su@suse.com>]

Coreutils commit 3cb862ce5f10 ( mv: better diagnostic for 'mv dir x' failure)
was released in v9.4, changed the error message from
'mv: cannot move 'b/t' to 'a/t': Directory not empty' to
'mv: cannot overwrite 'a/t': Directory not empty' in case of
EDQUOT/EEXIST/EISDIR/EMLINK/ENOSPC/ENOTEMPTY/ETXTBSY.

The change breaks generic/245 due to the mismatched output:

generic/245 1s ... - output mismatch (see /root/xfstests-dev/results//generic/245.out.bad)

Filter out the common part of mv error messages to fix the test.
