CSIT-441 vhost - Parametrized qemu install

Update the current QEMU installation script with option to override QEMU
installation and to apply additional patches. Additional patches are
applied from qemu_patches directory and subdir for specific QEMU version by
run-parts. This means that all patches for particular version are
applied.
All keywords for build QEMU are updated.
