[HTTPS-Everywhere] Trailing whitespaces

[Christophe Jarry]

Dear developers,

When I want to patch IceCat 3.6.13 source code to get the extracted version of
https-everywhere, quilt gives me the following warnings:

    Warning: trailing whitespace in lines 25,27,40,59,64,66,68,70 of
chrome/content/rules/GoogleServices.xml
    Warning: trailing whitespace in lines 10,22,61 of

I think it would be good to fix this, thanks.
