os: sysctl-based Executable implementation for NetBSD
FreeBSD and Dragonfly have used the sysctl method for years, while
NetBSD has read the name of the executable from /proc. Unfortunately,
some folks are hitting errors when building Go software in a sandbox
that lacks a mounted /proc filesystem.
Switch NetBSD to use the same implementation as FreeBSD and Dragonfly.
Unfortunately, the order of the arguments in the MIB is also
OS-dependent.
