binder-test: increase the memory sizes for the test service

The trusty_binder_test app on Android now has a test that
starts 32 threads that connect to our service simultaneously.
This requires more heap size than the current 8K, so we increase
the heap size for the test service to 64K.

Another new test makes a series of nested transactions which
require a lot more stack, so we also increase the stack limit
to 16K.
