feat: Add alternative hint code for hint on _block_permutation used by 0.10.3 whitelist

[fmoletta]

The method _block_permutation (in common/cairo_keccak/keccak) has the following string:

        from starkware.cairo.common.keccak_utils.keccak_utils import keccak_func
        _keccak_state_size_felts = int(ids.KECCAK_STATE_SIZE_FELTS)
        assert 0 <= _keccak_state_size_felts < 100

        output_values = keccak_func(memory.get_range(
            ids.keccak_ptr - _keccak_state_size_felts, _keccak_state_size_felts))
        segments.write_arg(ids.keccak_ptr, output_values)

While the 0.10.3.json whitelist contains the same hint with the first line changed to:
from starkware.cairo.common.cairo_keccak.keccak_utils import keccak_func

Both hints behave the same, as common/cairo_keccak/keccak_utils just imports everything from common/keccak_utils/keccak_utils

So now both code strings lead to the same hint function
