machinectl: don't show ".host" pseudo-machine in list by default

Let's hide all machines whose name begins with "." by default, thus
hiding the ".host" pseudo-machine, unless --all is specified. This
takes inspiration from the ".host" image handling in "machinectl
list-images" which also hides all images whose name starts with ".".
