email_log: Do not use bootstrap css for radio buttons.

We add the CSS rules handled by bootstrap for the radio
buttons in forward email modal to email_log.css as we
are in process of removing bootstrap

The elements for which CSS rules have been added are label
with "radio" class and "radio" type input elements.

The max-height property added to label by bootstrap is not
added since it does not applies to non-replaced inline
elements.
