void: Add checkpoints to void runner levels (#2366)

In the Loom Lounge yesterday, Stephen noticed that when I was caught in
void_runner, there was no Knitwitch when I respawned.

I don't think we strictly need to have Knitwitches at the start of every
level where you might be defeated. If you are caught by the very first
guard in the musician quest stealth level, you just respawn at the start
of the level, no witch.

However, perhaps it's reassuring to have one at the start of
void_runner. Having done that, maybe we can also put one after the
tricky three-needle crossing in void_grappling_round_2, and then also at
the start of that scene for good measure.

There is no good place (other than the very start) to put one in
void_grappling round 1.
