add OpenBSD unveil support
The unveil() system call first appeared in OpenBSD 6.4.
For stagit it has the following properties now:
- stagit-index: only read-access to the file-system for the specified
directories/repositories.
- stagit: read-access to the specified directory/repository.
read-write and creation access to the current directory for the output files.
read-write and creation access to the specified cache file.
