Without the dependency on cmake-modules, `bitbake eigen-conversions`
can possibly fail with:

```
| CMake Error at /home/lukas/dev/openembedded.org/openembedded-core/build/tmp-glibc/work/i586-oe-linux/eigen-conversions/1.11.8-r0/recipe-sysroot-native/opt/ros/indigo/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
|   Could not find a package configuration file provided by "cmake_modules"
|   with any of the following names:
|
|     cmake_modulesConfig.cmake
|     cmake_modules-config.cmake
|
|   Add the installation prefix of "cmake_modules" to CMAKE_PREFIX_PATH or set
|   "cmake_modules_DIR" to a directory containing one of the above files.  If
|   "cmake_modules" provides a separate development package or SDK, be sure it
|   has been installed.
| Call Stack (most recent call first):
|   CMakeLists.txt:5 (find_package)
|
|
| -- Configuring incomplete, errors occurred!
```

The failure only occurs if cmake-modules has not been installed
before eigen-conversions is configured. Hence, the regular
regression testing with `bitbake core-image-ros-world`, which
builds many packages in parallel, did not uncover this because
make-modules was usually installed before eigen-conversions was
configured.

However, the issue is clearly reproducible with
`bitbake eigen-conversions cmake-modules -c cleanall && bitbake eigen-conversions`

The missing dependency was probably introduced by the automatic
recipe updates without checking for new dependencies.

The patch provided upstream is incorporated since 1.11.4 and hence
is removed.

This commit further adds a simple fix to the patch for the ros-comm
repository.

Resolves:
  File "/usr/lib/python2.7/site-packages/tf/transformations.py", line 174, in <module>
    import numpy
ImportError: No module named numpy

When CATKIN_ENABLE_TESTING is deactivated, the ROS packages do not
require the rostest package.
This commit includes a number of patches to be submitted in the
upstream repositories and removes the rostest dependencies from
the recipes.

The tf recipe is updated to 1.10.6 to be in line with
https://github.com/ros/rosdistro/blob/9cb0c7fb0565614f2b5482a8a6c9411ad7bf257c/hydro/release.yaml.

The previously applied patch is incorporated in the hydro release
version of the tf package. Also, the new tf package has further
dependencies.
