While here, use PKGTAG.python- prefix & fix PLIST

The renaming affects the following packages:

- wip/pal-hardware-gazebo-melodic
- wip/pal-hardware-gazebo

This works well on Arch…

to fix configure when GMOCK_FOUND is not set.

Bump PKGREVISION to 1
Add missing headers.

[wip/talos-ros-control]->[wip/ros-control]

Setting CMAKE_PREFIX_PATH is useless. Since each dependency may be located in
its own path, one must pass to cmake the proper _DIR variables.

This is handled automatically by mk/sysdep/cmake.mk when a dependency
SYSTEM_SEARCH variable lists the *Config.cmake files whose path must be fed to
cmake.

Needed to access specific part of talos-ros-control.

- Connect the toplevel Makefile
- Prevent binary/source redistribution (according to the LICENSE)
- Drop inclusion of ros-basæMakefile.common: this is not a ros package
- Drop wrong python substitutions (with non existing files)
- Add missing dependencies, in particuler C and C++ compilers
- Whitespace/formatting cleanup in the depend.mk

This package is closed for now. It is a roscontrol version modified by PAL-robotics to
overcome some limitations. This package is for now under the openhrp-grx license.
