luci-theme-bootstrap: simplify login dialog

Use an traditional HTML form with post submit action to the same URL in
order to simplify the login process and not rely on the discarded login
XHR reply properly setting the login cookie.

This will also avoid one useless request on login and hopefully fix login
issues reported with various browser environments.

As a bonus, the resulting code is somewhat smaller as well.
