Enable/disable module/extension checkbox does not get needed margin

Adding patch that adds a min-width of 25px for #system-modules td.checkbox

Result:

This is on 8.0.x (HEAD is now at f6312b8) and no changes made.

To reproduce: Go to admin/config page and check the list of core modules, field types, multilingual and web services. Resize the window so that it is less than 1130px (with navbar horizontal). At that point the checkbox is already without margin. (The mobile view is ok)

You will not see the problem for field types, multilingual or web services (in English) since the text describing them is short. If you edit the DOM and make it longer you will see the checkbox behave the same way.

My Chrome version is 37.0.2062.94 Mac.

This is the checkbox (td class) computed CSS from the DOM - see any difference there if the steps above did not help in reproducing?

font-style: normal;

margin-right: 5px;
margin-top: 0px;
padding-bottom: 10px;
padding-left: 0px;

padding-top: 10px;
text-align: center;
vertical-align: top;
white-space: normal;
width: 12px;

Also tried a fresh install with the minimal install setup, and just seven theme enabled. Same behaviour.

Checked what alpha14 looked like on simplytest.me and got the same result. Checked that on an other computer and got the same result.
