    Fix kill of processes created by win32_create_inferior
    
    handle_v_kill uses signal_pid because win32 doesn't support multi-process.
    
    Without this gdb just refuses to kill the process:
    (gdb) kill
    Kill the program being debugged? (y or n) y
    Sending packet: $vKill;a410#33...Packet received: E01
    Packet vKill (kill) is supported
    Can't kill process
