Update sizes expectations since static linking ffmpeg.

Update sizes expectations since static linking ffmpeg.

This updates bss sizes for the following:
- linux-release-64/sizes/chrome-bss/bss
- linux-release/sizes/chrome-bss/bss
- mac-release/sizes/ChromiumFramework/ChromiumFramework
- xp-release/sizes/chrome_child.dll/chrome_child.dll

Change https://codereview.chromium.org/1141703002/ causes ffmpeg
to be statically linked into chrome (or chrome_child on windows).

While chrome/chrome_child have grown significantly, the net change
(now that ffmpegsumo.dll is gone) is actually a savings of a few
hundred KB due to dead code elimination in static linking.

(Bugs motivating the original static linking change)
