bug#53783: 29.0.50; eshell/sudo and eshell/su always use localhost as host

[Russell Sim]

Hey,

When using eshell if I call `sudo pwd` it will open a different host to if i
call `cd /sudo::/ && pwd` in the first case it will visit 
"/sudo:root@localhost:" and in the
other case it will visit my system "/sudo:root@mowgli:"

I would like to have them both visit the host's actual name "mowgli" so
that i can reduce the number of open sessions and also take advantage of
being able to store sudo passwords.

Would it be reasonable for eshell/sudo and eshell/su to instead either
use tramp-default-host or tramp-system-name which ever is more
appropriate?

Many thanks,
Russell
