IMPALA-6109: xfail TestHdfsUnknownErrors::test_hdfs_safe_mode_error_255

Browse Source 
The test puts the HDFS name node into safe mode to trigger an "Unknown
Error 255" and verifies that the error details can be obtained correctly
via the libHDFS API. However, putting the name node into safe mode can
trip up HBase (HBASE-18738), which causes sporadic failures of our other
HBase tests. To prevent this, we xfail the test until the HBase issue
has been addressed (or we find a better way to trigger a 255 error).
IMPALA-6212 tracks re-enabling the test in the future.
