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. Signed-off-by: Leah Rowe <leah@libreboot.org>
