```
stage2: fix memory leak of emit_bin.sub_path

Instead of juggling GPA-allocated sub_path (and ultimately dropping the
ball, in this analogy), `Compilation.create` allocates an
already-exactly-correct size `sub_path` that has the digest unpopulated.

This is then overwritten in place as necessary and used as the
`emit_bin.sub_path` value, and no allocations/frees are performed for
this file path.

```
