Restore < to format string

[1ec5]

Undid an unexplained change to a format string that changed the string’s meaning. A couple localizations had already localized the “<” to something locally appropriate, while others had removed the “<” in keeping with the base string.

The motivation for removing < from the UI was aesthetic and using a language not only engineers speak. Most navigation UIs seems to use 1 as the minimum for time remaining. I'd prefer that and perhaps spell out "less than".

I’m not sure how the arithmetic less-than sign is any more engineering-centric than an abbreviation like “mi” or “ft”. But I’m in favor of spelling out “less than” if we also spell out “miles” and “feet”.

Otherwise, as I mentioned in #457 (comment), if there’s no need for a “<” or “less than” (or the localized equivalent), then there shouldn’t be a format string in the first place.
