Subject: [PATCH] tty: assume posix systems support posix.empty_sigset

It should be pretty safe to assume that posix.empty_sigset
is supported on most, if not all, posix systems. Individual
OSes that need a different default value may add a case to
the switch like macos.

This should open up support for most other posix systems.

closes #151
