util/*: Properly detect OpenBSD for pledge() call
...
The utils that are pledged checked HAVE_PLEDGE which was
bogus. OpenBSD defines __OpenBSD__, which you can check
for in ifdef.
This change makes nvmutil and spkmodem-recv *actually*
use pledge, when the utils are compiled on OpenBSD.

util/spkmodem_recv: Use pledge but only on OpenBSD
...
It will only be used on OpenBSD. Other operating
systems will behave in the same way.
Pledge is feature specific to OpenBSD that
restricts system operations, for security:

util/spkmodem_recv: Add -u flag (no line buffer)
...
printf outputs to stdout, which is line buffered
by default.
Adding a -u option to disable buffering.
Exit when a non-support flag is given, but adhere
to current behaviour when no flag is given.

They do not need to be initialised zero, because

This is a client for spkmodem, to allow serial
console via PC speaker.
I've decided to import it in lbmk, because I
heavily modified it. The patches will be
applied next.
