machine: prepend LocalhostSSHArgs to args

Rather than append LocalhostSSHArgs to args, prepend it, assuming the
order doesn't matter here.

This fixes the following prealloc warning (without decreasing
readability):

> cmd/podman/machine/cp.go:130:2: Consider preallocating args (prealloc)
> 	args := []string{"-r", "-i", sshConfig.IdentityPath, "-P", strconv.Itoa(sshConfig.Port)}
> 	^

This commit is part of series fixing issues reported by prealloc linter
from golangci-lint v2.8.0.
