protobuf: disable protoc binary for target

When applications want to use protoc during the build, the target binary
has to be disabled in order to avoid following error:

|   The imported target "protobuf::protoc" references the file
|
|      "<application build dir>/recipe-sysroot/usr/bin/protoc-<protobuf version>"
|
|   but this file does not exist.  Possible reasons include:
|
|   * The file was deleted, renamed, or moved to another location.
|
|   * An install or uninstall procedure did not complete successfully.
|
|   * The installation package was faulty and contained
|
|      "<application build dir>/recipe-sysroot/usr/lib/cmake/protobuf/protobuf-targets.cmake"
|
|   but not all the files it references.
