Optimize Qemu installation to speed up vhost tests

Currently Qemu is being installed if there is a change of qsz parameter
between tests/suites. Qemu is installed always into the same directory. This
patch changes the default behavior to install qemu over and install
pathced version to separate directory. It also disables force install.
