[YOCTO #12493] Fixed: - qemu started with pid 10000 - qemu exited unexpectedly - The pid 10000 is re-used by another different process. The is_alive() returned True in such a case because both qemu_pidfile and /proc/10000 exist, but it's another process, this patch fixed the problem.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
