[PATCH] isar-installer: Generate textual output only in unattended mode.

["alexander.heinisch via isar-users" <isar-users@googlegroups.com>]

From: Alexander Heinisch <alexander.heinisch@siemens.com>

Dialog renders textual output unreadable, thus, useless.
Thus, logs output via a serial, or piped to a file are useless when combined with dialog.
