Fix hadoop short circuit reading can not enabled in some environments. - Revert #21430 because it will cause performance degradation issue. - Add `$HADOOP_CONF_DIR` to `$CLASSPATH`. - Remove empty `hdfs-site.xml`. Because in some environments it will cause hadoop short circuit reading can not enabled. - Copy the hadoop common native libs(which is copied from https://github.com/apache/doris-thirdparty/pull/98 ) and add it to `LD_LIBRARY_PATH`. Because in some environments `LD_LIBRARY_PATH` doesn't contain hadoop common native libs, which will cause hadoop short circuit reading can not enabled.
