hostnamectl: rework pretty hostname validation (#3985)

Rework 17eb9a9ddba3f03fcba33445c1c1eedeb948da04 a bit.

Let's make sure we don't clobber the input parameter args[1], following our
coding style to not clobber parameters unless explicitly indicated. (in
particular, as we don't want to have our changes appear in the command line
shown in "ps"...)

No functional change.
