Remove style tags from svg

The style tags in the svg inline images will trigger an issue when the
browser attempts to interpret them, and flags them as inline-styles
(which we want to disallow via policy).  This commit removes them,
which, given that they shouldn't have been there in the first place,
should have no ill effects.

Tested By:
Launched GUI, observed button behavior did not change
