[PATCH v1 2/6] start_vm.py: Fix target name handling

[Anton Mikanovich <amikan@ilbers.de>]

From: Roman Pletnev <rpletnev@ilbers.de>

This patch fix bb_output search (issue with wrong arch name being
selected for qemu). It also add mipsel to the list of supported
architectures, add options -o (output file) and -p (pid file).
