Fix Aruba AOS-CX sh sys vendor line

[mjbear]

resolves #2168

• Fix vendor line where AOS-CX is used instead of ArubaOS-CX
• Replace literal whitespace with regex
• Trim trailing tabs from template file
• Update template to trim trailing whitespace from product in parsed output (of 5.yml)
  • None of the other raw data have trailing whitespace on each line (like that provided on Aruba-AOSCX sh system parser broken #2168)

@mjbear in tests/aruba_aoscx/show_system/show_system5.yml, should the parsed vendor be HPE ANW instead of HPE?

Yeah, it can probably be updated to catch both vendor words. 😐
This was the first set of output with more than one word for the vendor name. 😉
