Use HOME before /etc/passwd to find id_dropbear (#137)
Currently dbclient uses the value of HOME by default when looking for
~/.ssh/known_hosts, falling back to /etc/passwd if HOME is not set (so
that people can work around broken values in /etc/passwd).
However, when locating the default authentication key (defaults to
~/.ssh/id_dropbear), paths not starting with / are always prefixed with
the value from /etc/passwd.
Make the behaviour consistent by adjusting expand_homedir_path to use
the value of HOME, falling back to /etc/passwd if HOME is not set.
