Fix: Remove unwanted extra args

Fix: Remove unwanted extra args

RSA/SHA-1 was deprecated since the OpenSSH release 8.8.
This causes builds with latest version of packer to fail with the
below error:

Error:

Data could not be sent to remote host "127.0.0.1". Make sure this
host can be reached over ssh: command-line: line 0: Bad
configuration option: pubkeyacceptedalgorithms.

Add workaroud and pass required HostKeyAlgorithms through ssh extra
argumements. Testing with cloud builds and since we are using multiple
flavors the only options required are "IdentitiesOnly=yes"
and "HostKeyAlgorithms=+ssh-rsa".
