[Buildroot] ninja/python-meson packages

Hi,

+ Eric Le Bihan who first proposed ninja/meson support.

The current gstreamer1 version in Buildroot is 1.8.3.
The support for meson was added in 1.9.2. So upgrading gstreamer1 is 
certainly necessary before merging Meson support.

Roughly, add dependency on ninja, add an option in cmake configure step 
(-G ninja) and use ninja instead of make in build and install commands.

That sounds good to me :)

An option in "Build options" is definitely more appropriate. In the 
first place I had just added it in package/cmake/Config.in - which made 
it appear in target development tools.
Then I will check with several existing CMake packages in buildroot.

Regarding Meson integration, I think that Eric - if he's still 
interested in working on that - is the right person. I understand that 
his patches didn't provide pkg-meson.mk yet, but he proposed to do so. 
Am I right?
