finagle-thrift: Add scala to tracing BUILD file

Problem:

I need to deal with zipkin data stored in an offline context, using
scala. The finagle-thrift BUILD file for tracing.thrift doesn't specify
a target for generating scrooge classes.

Solution:

Add a target for generating scala bindings

Result:

There is now a target for generating scala bindings of the contents of
tracing.thrift
