targets/xvmc-nouveau: convert to static/shared pipe-drivers

Similar to vdpau targets, we're going to convert the individual
target libraries into a single one.

The library can be built with the relevant pipe-drivers
statically linked in, or loaded as shared modules.
Currently we default to static.
