qemurunner.py: refactor searching for QEMU PID
Ask QEMU to store the QEMU process PID in a file, this way we don't have to parse running processes and analyze descendents. This is done via QEMU command line argument "-pidfile". [YOCTO #12001] (From OE-Core rev: 67612dcd2a8a1aa1d683dddb0bd2f592886ff020) (From OE-Core rev: 9fe7aa1824666d3f7ceb085bef59026e245cb752) Signed-off-by: Juro Bystricky <juro.bystricky@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org> Signed-off-by: Armin Kuster <akuster808@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
