qemurunner: Sanitize output from qemu and qemu pid
Currently the output from qemu could contain control or Unicode characters; having such characters in the log will cause an internal server error when sending the report to error reporting web. Control characters can be found in the command line used to run quemu too. This change sanitize the output from qemu and the command line used to run qemu, this way the logs doesn't contain control or Unicode characters and this will solve the issue of error reporting web and generate better logs. The only Unicode character found in the qemu output is the copyright symbol, it really doesn't interfer removing Unicode characters with debugging.
