Fix crash when using Pathspec in StatusOptions
Using `StatusOptions.Pathspec` results in a fatal error panic with
the message 'unexpected signal during runtime execution'.
This is because the `&cpathspec` C.git_strarray gets freed in
`*StatusOptions.toC()` before being passed to
`C.git_status_init_options()` in `*Repository.StatusList()`
(see https://github.com/libgit2/git2go/blob/b3e7705c48f038ef335204a2a9e1ee829784c30e/status.go#L138)
The relevant panic trace is:
```
