This commit add the name of the Qemu defconfig file after each
qemu command line in order to retrieve it easily.
Since a readme.txt can be shared between several Qemu defconfig, we
need at least one qemu command line in readme.txt for each defconfig.
For now, ignore the qemu_arm_vexpress_tz_defconfig since it fail to build
due to python script issue [1]. Anyway the arm vexpress boot is tested
with qemu_arm_vexpress_defconfig.
