Have to invalidate the mute button when changing the volume

[Ryosuke Niwa]

Consider merging https://chromium.googlesource.com/chromium/blink/+/c4c685c82908449526fd8c251cc551e729ebed08

This is because the painting code in
RenderMediaControlsChromium.cpp:paintMediaMuteButton depends on the
volume, and that code gets called via RenderTheme, so nothing else can
invalidate the button.
