Fix failing cardio test and make sprinting distance less random

[wapcaplet]

Summary

Bugfixes "Fix failing cardio test and make sprinting distance less random"

Purpose of change

Test cases I added in #53603 were sometimes failing due to randomness in the stamina regen and movement code.

Describe the solution

• Make stamina regen non-random - when regen is 19.4, always round up to 20.0 instead of only having a 40% chance of rounding up to 20.0 - that is, simply replace roll_remainder with std::ceil in the update_stamina function
• Remove the random chance to become winded when below 20% of maximum stamina - instead, become winded only when stamina runs out - in the game::on_move_effects function
• Adjust the test case for new expectations (some are 1 step higher than before)

Describe alternatives you've considered

Testing

Run tests/cata_test '[cardio]'

or many tests:

for i in {1..100}; do ./tst --rng-seed $i '[cardio]'; done
