populate_sdk_ext.bbclass: remove the try...finally

The "sdkbasepath + '/conf/local.conf.bak" doesn't exist when
"oe.copy_buildsystem.check_sstate_task_list()" fails, then os.replace() would
raise FileNotFoundError, which overcomes the real error. Keep the error status
makes debug easier, so remove the try..finally.
