[KVM-AUTOTEST PATCH 3/4] kvm_tests: Use autotest log files to scan results

[Lucas Meneghel Rodrigues <lmr@redhat.com>]

The 'autotest' kvm subtest was relying on autotest output, that
now has the logging line prefixes. The logging line prefixes
breaks the results parser, so we would either have to make the
parser to strip the logging prefixes or read autotest status
files generated on the results directory. The later is a simpler
approach, so this patch implements it.

Also, copy control files defined inside
self.bindir/autotest_control directory to the guest. This way
we can create more complex control files to run in guests
without having to touch other tests directories.
