Migrate warning

 When clicking in the form fields to set a custom time or date format in
 options-general.php, the radio input in front of the text field gets
 automatically selected with jQuery.

 This results in a jQuery Migrate warning:

 {{{ JQMIGRATE: jQuery.fn.attr('checked') may use property instead of
 attribute }}}

 The attached patch replaces the use of `$.attr()` with `$.prop()` which
 seems to be the preferred way according to the
 [http://api.jquery.com/prop/#prop2 jQuery documentation]. This silences
 the warning.
