[SPARK-23089][STS] Recreate session log directory if it doesn't exist

## What changes were proposed in this pull request?

When creating a session directory, Thrift should create the parent directory (i.e. /tmp/base_session_log_dir) if it is not present. It is common that many tools delete empty directories, so the directory may be deleted. This can cause the session log to be disabled.

This was fixed in HIVE-12262: this PR brings it in Spark too.

## How was this patch tested?
