android: Tweak the location that the android template is written to so that the compare_pot script can find it.

Add script (buid_pos) for generating all templates and comparing

This may fix, or at least shed light on, a bug where the client
repeatedly requests work for a resources that already has plenty.

 - Show the OpenCL platform vendor for each OpenCL CPU description.
 - OpenCL may not reliably report total RAM, available RAM and max FLOPS for CPUs, so exclude these from the OpenCL CPU descriptions; that information is available elsewhere.
