[Buildroot] [for-next: v4: 2/2] package/solatus: new package

[Romain Naour <romain.naour@gmail.com>]

Sample quest and testing quest are not included in SOLARUS_LICENSE
since it's notinstalled by default.

Remove Werror when building with debugging symbols.

Add libpng runtime dependency since solarus games require png image
support.

Q: The SDL2 Solarus support seems to needs at least one video renderer
   (directfb, x11 or kms/drm) but the Salurs package selects none.
   It's not explicitely listed in the build instructions:
   http://www.solarus-games.org/development/compilation-instructions
   How can we add a dependency on without introducing circular dependency
   on SDL2 package?
   As reported by Julien, if no video renderer is selected solarus doesn't
   start. But selecting a video renderer is an user choice depending on
   the target.

v4: add license file hash
    Add libpng runtime dependency
v3: no change
v2: add DEVELOPERS entry
    Add a note in help text about Salarus games
    Add license hash.
