yujin_ocs: 0.5.3-1 in 'hydro/distribution.yaml' [bloom]

Increasing version of package(s) in repository `yujin_ocs` to `0.5.3-1`:

- distro file: `hydro/distribution.yaml`
- bloom version: `0.5.9`
- previous version for package: `0.5.3-0`

## yocs_cmd_vel_mux

```
* Added support for YAML-CPP 0.5+.
  The new yaml-cpp API removes the "node >> outputvar;" operator, and
  it has a new way of loading documents. There's no version hint in the
  library's headers, so I'm getting the version number from pkg-config.
  This part of the patch is a port of the ones created by @ktossell for
  map_server and other packages.
  The new yaml-cpp also does not have FindValue.
