[SPARK-25741][WebUI] Long URLs are not rendered properly in web UI
## What changes were proposed in this pull request?
When the URL for description column in the table of job/stage page is long,
WebUI doesn't render it properly.

Both job and stage page are using the class `name-link` for the description
URL, so change the style of `a.name-link` to fix it.
## How was this patch tested?
