Commit f2243b76b56c0a29bc252cdacec8ae53de88b327 in impala's branch refs/heads/master from Riza Suminto

IMPALA-14557: Fix flaky test_show_files_partition
TestIcebergTable.test_show_files_partition is unstable because files are
alphanumerically sorted and the order between a random UUID and
"delete-*" is not guaranteed.
This patch fix the flakiness by specifying VERIFY_IS_SUBSET and using
negative lookahead of "delete" word to detect valid Iceberg data file.
Testing:
- Loop and pass test_show_files_partition 50 times. Before, it can fail
in less than 10 loops.
