strip .po file suffix in translation statistics

The goal is to get the statistics to line up in
columns and not exceed an 80 character line which might
cause wrapping. Removing .po suffix from the translation
name gives us 3 extra characters. Formatting problems were
observed when bn_IN.po was added.
