Rename loop variable in `src/eval.c's unwind_to_catch()

Rename loop variable in `src/eval.c's unwind_to_catch()

[Chris Gregory]

Change last_time to found_catch.  This more clearly expresses the
meaning of the loop, rather than just saying that this variable
controls when it breaks, which is obvious.
