Subject: [PATCH 14/25] Only update attributes given on the command line

When updating attributes of the LDAP computer object we only want to
update attributes which are related to options given on the command
line. Otherwise a simple call of 'adcli update' to check if the machine
account password needs an update might unexpectedly reset other
attributes as well.
