util/nvmutil: harden pledge/unveil calls (OpenBSD)
*Open* files at the start, then unveil. The same overall
behaviour is observed. In the case that invalid arguments
are given, simply opening a file does not cause much
performance impact (if any).
Restrict operations as early as possible in code.
Bonus:
writeGbeFile also hardened; if flags is O_RDONLY, it aborts.
