[isar-cip-core][PATCH 6/7] enhance start-qemu.sh for arm64 secure boot

[sven.schultschik@siemens.com]

From: Sven Schultschik <sven.schultschik@siemens.com>

The start-qemu shell script need some adjustments to switch on secure in the machine statement and adds the virtual random number generator if secure boot is enabled.
