www-client/chromium and "missing" libffmpegsumo.so

Gentoo, similarly to other Linux distributions, avoids bundled libraries in its packages. One of www-client/chromium's dependencies is ffmpeg, and in Gentoo it's unbundled when possible (sometimes upstream makes very incompatible changes).

What people see are console errors like these:

[154:154:175949833148:ERROR:base/native_library_linux.cc(28)] dlopen failed
when trying to open /usr/lib64/chromium-browser/libffmpegsumo.so:
/usr/lib64/chromium-browser/libffmpegsumo.so: cannot open shared object file:
Permission denied

Those messages can be safely ignored, and are not symptoms of a bug. They just mean we have removed the bundled libffmegsumo, so it's no longer there.

I hope you like it - less bundled libraries!
