```
getenv: remove unnessary `small key` block

The code removed does unnecessary copying in order to create a null-terminated pointer, just to pass it to libc getenv. It only does this for `small keys`, which are under 64 bytes in size.

Instead of going out of the way to add a null byte to a function that takes normal slices, this should just be handled by the loop below, which scans c.environ to find the value
```
