Allows renamed lints
Allows renamed lints

We got a warning saying that "non_fmt_panic" has been renamed to
"non_fmt_panics", however we don't want to rename the lint as it
presumably limits the MSRV. Instead, we allow the renamed lints and
if/when the lint gets removed it will become a hard compile error.
