Exclude test cases for data types %lld, %llu, %llx to reduce build binary size

The "minimal_printf" greentea test has test cases for the different data types
(%d, %u, %x, %ld, %lu, %lx %llx)  that require a minimum above 36kb ROM
to build all test cases. LPC1114 target has only 32KB ROM memory,
so these changes excluding 3 test cases of data types %lld, %llu, %llx
to bring down to meet target minimum ROM size
