Merge runqemu features into poky-qemu

This merges the functionality of the runqemu script into poky-qemu.
It also removes the requirement to order command line args to poky-qemu
in any particular order.

This fixes a slew of runqemu-related bugs by making the runqemu script
obsolete (and fixing the issues in the new poky-qemu), including
[BUGID #294] [BUGID #295] [BUGID #371] and [BUGID #324].
