Make deploy script delete tarball

The deploy script does not delete the file it transfers to an Amplipi, this means we end up using a ton of storage space on testing Amplipis we often deploy to via the script.

pardon, I'm reopening this; my deploy just bailed on me with this:

Add desktop icon for Config Streamer : [[]]
Add desktop icon for Aux Input : [[]]
Reboot os : [[]]
Connection to amplipi.local closed by remote host.
Connection to amplipi.local closed.
