ggml : android and old glibc NUMA incompatibility bugfixes (#5557)

* #ifdef out some code NUMA blocks for Android due to lack of support

* added in some __ANDROID__ if def gates around numa code and forced GLIBC prior to 2.29 to use a syscall for getcpu instead of the wrapper

* Changed gates on numa platform specific stuff to __gnu_linux__ to skip any platforms without glibc

* harmonizing #if defined blocks for numa code to __gnu_linux__ since that's the only model that's being followed anyways
