ANDROID: Reduce perturb table size for microdroid kernels

The current configuration for the perturb table size results in a 256 KB
allocation being made at boot. This memory is not used by microdroid,
since there is no requirement to support a networking stack. Therefore,
reduce it to be as small as possible, which drives down the allocation
size to just 4 KB.
