Per the GDB remote protocol documentation
https://sourceware.org/gdb/current/onlinedocs/gdb/Packets.html#index-vKill-packet
the debug stub is expected to send a reply to the 'vKill' packet. At
least some versions of GDB crash if the gdb stub simply exits without
sending a reply. This patch fixes QEMU's gdb stub to conform to the
expected behavior.
Note that QEMU's existing handling of the legacy 'k' packet is
correct: in that case GDB does not expect a reply, and QEMU does not
send one.
