api: Define protobuf for BGP Capabilities

Example of protoc command:
$ export PROTOBUF=${HOME}/protobuf/src
$ export GOBGP=${GOPATH}/src/github.com/osrg/gobgp
$ protoc \
    -I ${PROTOBUF} \
    -I ${GOBGP}/api \
    --go_out=plugins=grpc:${GOBGP}/api \
    ${GOBGP}/api/gobgp.proto \
    ${GOBGP}/api/attribute.proto \
    ${GOBGP}/api/capability.proto
