Subject: ectool: Support OpenBSD

Adds checks for OpenBSD in all the places that were already checking for
NetBSD. This fixes e.g.:

    ec.c:21:20: error: sys/io.h: No such file or directory

which was caused by defaulting to Linux.

Also, OpenBSD calls its amd64 iopl amd64_iopl instead of x86_64_iopl.
This change just defines iopl appropriately depending on the
OS and architecture.

TEST=Build on OpenBSD 6.0 or -current from 2017-01-25.
