kas: add QEMU emulation

Added the instruction to build the image with OpenDDS for QEMU with kas.

With QEMU it is possible to run the testsuite of OpenDDS without
real hardware target.

This could be used for regression testing.

Note that building the image with the ishapes demo is not possible for QEMU.
