IMPALA-10441: Skip test_bytes_read_per_column if not on local minicluster
IMPALA-9865 part 2 made some expected outcomes of the above test steps
stricter. Unfortunately these stricter results are only valid when the
tests are run on an HDFS file system in the context of a local
minicluster, breaking the same test on S3 and EC storage.
The patch disables the test step when run outside the context of a local
minicluster HDFS.

> The test fails for all debug actions exercised in the test set.
> Error backtrace is:
> {code}
> query_test/test_scanners.py:1006: in test_bytes_read_per_column
> assert len(compressed_bytes_read_per_col_summaries) == 4
> E assert 2 == 4
> E + where 2 = len([TSummaryStatsCounter(total_num_values=0, name=None,
> max_value=0, sum=0, min_value=0, unit=None),
> TSummaryStatsCounter(total_num_values=0, name=None, max_value=0, sum=0,
> min_value=0, unit=None)])
> {code}
> The symptom on builds testing HDFS erasure-coding is slightly different (the
> mismatching number is different):
