i965: Link compiler unit tests to libi965_compiler.la

We can now link the unit tests against just libi965_compiler.la. This
lets us drop a lot of DRI driver dependencies, but we still pull in all
of libmesa and more.

This also provides a few standalone users of libi965_compiler.la, which
will help us accidentally using i965_dri.so functions from the compiler.
