Fix a layout issue in the input method list in the language options on Chrome

Before the fix, we didn't have any space between a checkbox and the input
method name, which looked bad.

Note that we don't have this problem in other options pages, as our HTML
files are formatted like:

      <input id="foobar" type="checkbox">
      <span i18n-content="foobar">

the line break between two elements make a text node of a single space
inbetween.

BUG=chromium-os:11248
TEST=on chrome os, open the language options, see the input method list.
