tests: Initialize sigops draining script with bytes in feature_taproot

Browse source 
The sigops draining script in feature_taproot's block_submit was
initialized with a list that would end up always being iterated by
CScript's constructor. Since this list is very large, a lot of time
would be wasted. By creating and passing a bytes object initialized from
that list, we can avoid this iteration and dramatically improve the
runtime of feature_taproot.
