commented out checkstyle invocation in hcatalog/ module tests.
1) iterate.hive.tests: changed list order to be "standard";
2) iterate.hive.tests: added "shims" and "common" to the testing sequence.
merged diff "hive.2991.4.trunk.patch" from https://issues.apache.org/jira/browse/HIVE-2991: clover added to classpath in "ql/src/test/queries/clientpositive/input37.q".

fixed one more failure due to missing clover.jar in classpath.
