    oeqa/parselogs: Don't use cwd for file transfers
    
    If you run:
    
    MACHINE=A bitbake <image> -c testimage
    MACHINE=B bitbake <image> -c testimage
    
    and A has errors in parselogs, machine B can pick these up and cause
    immense confusion. This is because the test transfers the log files
    to cwd which is usually TOPDIR. This is clearly bad and this patch
    uses a subdir of WORKDIR to ensure machines don't contaminate each
    other.
    
    Also ensure any previous logs are cleaned up from any existing
    transfer directory.
