Trevor Gamblin b61d8bc577 qemurunner.py: add try/except for pid handling race
In some instances, attempts to remove the qemu pidfile within the
stop() method fail despite the os.path.exists() call immediately
before implying that the file is present. Add a try/except block
to log a warning if this occurs, rather than failing outright,
since the process simply appears to be exiting at an inconvenient
time.

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.
