package/kodi: add support for more architectures

For the autoconf-based build system it was necessary to allow each
supported architecture separatly:
https://github.com/xbmc/xbmc/blob/Krypton/m4/xbmc_arch.m4

For the CMake build system this is not necessary anymore so we only
blacklist archs in Config.in known to be broken.
