Do not make protos in gotools dir

The compile_protos.sh script tries to compile all protos in the fabric
directory.  Once the gotools dir is initialized, it contains some proto
files which will fail to compile with compile_protos.sh.

This change excludes the gotools directory from proto compilation.
