Move testnet ssh key (#5770)

* Factor out hardcoded testnet ssh key path

* Build/create test net ssh key path

* Rename testnet ssh dir

* Give testnetSSHDir a more generic name

* shellcheck

* favor hardcoded paths over `paths.sh`

* Put instance-startup-complete stamp in the scratch dir as well

* Rename `/solana` > `/solana-scratch`
