HyukjinKwon 7c05f61514 [SPARK-28130][PYTHON] Print pretty messages for skipped tests when xmlrunner is available in PySpark
## What changes were proposed in this pull request?

Currently, pretty skipped message added by f7435bec6a mechanism seems not working when xmlrunner is installed apparently.

This PR fixes two things:

1. When `xmlrunner` is installed, seems `xmlrunner` does not respect `vervosity` level in unittests (default is level 1).

    So the output looks as below

    ```
    Running tests...
     ----------------------------------------------------------------------
    SSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
    ----------------------------------------------------------------------
    ```

    So it is not caught by our message detection mechanism.

2. If we manually set the `vervocity` level to `xmlrunner`, it prints messages as below:

    ```
    test_mixed_udf (pyspark.sql.tests.test_pandas_udf_scalar.ScalarPandasUDFTests) ... SKIP (0.000s)
    test_mixed_udf_and_sql (pyspark.sql.tests.test_pandas_udf_scalar.ScalarPandasUDFTests) ... SKIP (0.000s)
    ...
    ```

    This is different in our Jenkins machine:

    ```
    test_createDataFrame_column_name_encoding (pyspark.sql.tests.test_arrow.ArrowTests) ... skipped 'Pandas >= 0.23.2 must be installed; however, it was not found.'
    test_createDataFrame_does_not_modify_input (pyspark.sql.tests.test_arrow.ArrowTests) ... skipped 'Pandas >= 0.23.2 must be installed; however, it was not found.'
    ...
    ```

    Note that last `SKIP` is different. This PR fixes the regular expression to catch `SKIP` case as well.

## How was this patch tested?

Manually tested.

**Before:**

```
Starting test(python2.7): pyspark....
Finished test(python2.7): pyspark.... (0s)
...
Tests passed in 562 seconds

========================================================================
...
```

**After:**

```
Starting test(python2.7): pyspark....
Finished test(python2.7): pyspark.... (48s) ... 93 tests were skipped
...
Tests passed in 560 seconds

Skipped tests pyspark.... with python2.7:
      pyspark...(...) ... SKIP (0.000s)
...

========================================================================
...
```

Closes #24927 from HyukjinKwon/SPARK-28130.
