Inline class styles

The characters in the OpenBMC logo use class styles 1 and 6.  SVGO for
whatever reason chokes on trying to deduplicate these, which causes a
template error when inlining the SVG, because style tags still exist.

Ideally in the future we would export our SVGs with inline styles, or
get SVGO to do it for us, but inline the styles manually for now.

Note, that build-on-openbmc-logo.svg has no style tags, and does this by
default, even though they are very similar images.

Tested: Loaded webui.  Logo loads properly.
