tools: Fix wrong instrumentation of binary comprehensions
When cover instruments binary comprehensions it's generating a
{block, ...} abstract code term inside a {bc, ...} term that is causing
the evaluation to fail at runtime. Removing the block statement
eliminates the error.
The template of a bit string comprehension cannot have a counter since
it is not allowed to be a block.
