targets/dri-nouveau: Convert to static/shared pipe-drivers

Similiar to other targets, we'd like to convert all the separate
targets into a single one, thus we'll minimize the duplication and
overall size of mesa. The conversion per API basis, with the drivers
available either statically or shared. Currently the former is the
default.

v2: Correctly append the version script to the linker flags.
