sudo password assumes host will have base64 command

[miah]

The base64 command is used to ensure the sudo password is not mangled when passed through train. Some systems, like HPUX and AIX do not have a base64 command, so this will error:

PS> inspec shell --backend=ssh --host=<omitted> --user=USER --password=$env:SudoPassword --sudo --sudo-options=“-u sudouser” --sudo-password=$env:SudoPassword
Sudo failed:  ksh: base64:  not found
Password:
sudo: pam_authenticate: Conversation failure

tbh it was also rather disturbing to see my password in the debug logs, even if superficially hidden by base64 encoding. we owe users better than allowing sensitive confidential data to be leaked in any trivially-discoverable way.
