Auto merge of #8678 - ehuss:fix-priv-test, r=alexcrichton

Fix nightly exported_priv_warning test.

Error messages have slightly changed due to rust-lang/rust#73996 to not include the full path.  I used a `[..]` match just in case anyone is still using a slightly older nightly, or if it changes again in the future.
