oeqa/utils/qemurunner: fix logging
OE-Core commit
519e381278d40bdac79add340e4c0460a9f97e17 unfortunately
broke logging in two different ways:
1) it prevented logging to the task log from working within bitbake
-c testimage. This is due to the logger object being set up too early
which interferes with BitBake's own logging. If we prefix the name
with "BitBake." everything works (and we don't need to set the
logging level).
2) Additionally because it called the log functions on the logging
module and not the logger object it set up, this caused the
oe-selftest logging to start printing everything from that point
forward.
Fix these two issues and return us to the desired behaviour for
do_testimage.
