[Merge to 2785] Hide the DIV containing password import/export buttons

The import/export feature for passwords is currently behind a flag. However,
the settings WebUI hides the controls instead of the containing DIV. As a
result, on loading the settings, the space for the controls is briefly
taken into consideration and a vertical scrollbar shows up.

This CL hides the containing DIV instead of the individual controls.

Test steps:
With chrome://flags/#password-import-export enabled, observe that about:settings/passwords looks the same as without the patch. With chrome://flags/#password-import-export disabled, observe that during reloading of about:settings/passwords, no vertical scroll bar is flashing/seen.
