virt test: Check windows bsod dump when unattended_install fail.

If unattended_install fail for windows guest and rename_error_image
set, image_copy will call rename the fail image. Then call
win_bsod_catch.py to check whether dump file is created in guest.
If yes, will try to analyze dump file with Windbg.

resolved conflict in  tests/image_copy.py and remove a blank space.
