Enable jumbo for media/filters

Building //media takes around 23 CPU minutes. A experimental
branch showed that this could be reduced, by using jumbo,
to around 9 CPU minutes. media/filters is the third largest part
of media and takes around 2 CPU minutes to compile without
jumbo.

This commit enables jumbo for media/filters.
