oeqa/targetcontrol: Rework exception handling to avoid warnings

We're seeing:

WARNING: bitbake/lib/bb/cookerdata.py:136: ResourceWarning: unclosed file <_io.FileIO
name='tmp/work/qemux86_64-poky-linux/core-image-minimal/1.0-r0/testimage/qemurunner_log.20200601181912'
mode='ab' closefd=True

which can only be caused by the qemu.stop() method not being called.
Tweak the error handling to fix the blanket exception handler which
is likely meaning this function isn't getting called.
