oeqa/targetcontrol: Attempt to fix log closure warning message

Browse Source 
We continue to see the warning message:

WARNING: lib/bb/daemonize.py:76: ResourceWarning: unclosed file <_io.TextIOWrapper
name='build/tmp/work/qemux86_64-poky-linux/oe-selftest-image/1.0-r0/testimage/qemurunner_log.20200703011821'
mode='a' encoding='UTF-8'>

I've been unable to reprodue this but believe its caused by garbage
collection of the FileHandler used in QemuTarget being delayed until
after a new tinfoil instance is created by a subseqent test.

Force the log file to be closed when we stop using it to avoid this.
