qemu: don't use deprecated -no-kvm-pit-reinjection

Since qemu-kvm 1.1 [1] (since 1.3. in upstream QEMU [2]) '-no-kvm-pit-reinjection' has been deprecated. Use -global kvm-pit.lost_tick_policy=discard instead. https://bugzilla.redhat.com/show_bug.cgi?id=978719 [1] http://git.kernel.org/cgit/virt/kvm/qemu-kvm.git/commit/?id=4e4fa39 [2] http://git.qemu.org/?p=qemu.git;a=commitdiff;h=c21fb4f (cherry picked from commit 1569fa14d8f6b6636cf78d7ee62ae3bd205f5638) Conflicts: tests/qemucapabilitiesdata/caps_1.2.2-1.caps tests/qemucapabilitiesdata/caps_1.2.2-1.replies tests/qemucapabilitiesdata/caps_1.3.1-1.caps tests/qemucapabilitiesdata/caps_1.3.1-1.replies tests/qemucapabilitiesdata/caps_1.4.2-1.caps tests/qemucapabilitiesdata/caps_1.4.2-1.replies tests/qemucapabilitiesdata/caps_1.5.3-1.caps tests/qemucapabilitiesdata/caps_1.5.3-1.replies tests/qemucapabilitiesdata/caps_1.6.0-1.caps tests/qemucapabilitiesdata/caps_1.6.0-1.replies tests/qemucapabilitiesdata/caps_1.6.50-1.caps tests/qemucapabilitiesdata/caps_1.6.50-1.replies (qemucapabilitiestest is not backported)
