Tomasz Zawadzki 14034200d9 test/bdevio: present info when RPC lib is missing from PYTHONPATH
The test.py script relies upon importing SPDK Python RPC libs.
This requires user to add ./spdk/scripts/ to PYTHONPATH.

Unfortunately --help could not be reached when the import failed,
to user executing the script directly wouldn't know that.

This patch adds instructions for user when importing
RPC lib fails.
