    oe-selftest: fix behaviour if oe-selftest.log is a dangling symlink
    
    If you delete the log file that the oe-selftest.log symlink points to
    but not the symlink itself, because we were using os.path.exists() here
    the code assumed that the symlink didn't exist when in fact it still
    did. Use os.path.lexists() instead.
