build: Add support for building on Illumos

This commit adds support for building for Illumos-derived operating
systems. Regrettably, the cyrpto/ssh/terminal package does not include
implementations of the functions IsTerminal, MakeRaw or Restore for the
solaris OS. Consequently this commit implements them in Vault.

makeRaw(fd int) is based on the Illumos implementation of the getpass
function [1] for the correct flags. isTerminal(fd int) is based on the
Illumos libc implementation [2] of isatty.
