Subject: [PATCH 2/2] build: use grpc++ pkgconfig to retrieve flags/libraries
References: https://github.com/vmware/open-vm-tools/pull/664

When a .pc file exists, it should be used. Fixes obvious linking problems like

ld: .libs/libcontainerInfo_la-containers.grpc.pb.o: in function `grpc::ByteBuffer::~ByteBuffer()':
/usr/include/grpcpp/support/byte_buffer.h:99: undefined reference to `grpc_byte_buffer_destroy'
collect2: error: ld returned 1 exit status
make[4]: *** [Makefile:649: libcontainerInfo.la] Error 1
