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.
