Subject: tests: Switch from unbuffer to ptyx

unbuffer is part of expect, which is not actively maintained.  This
recently led to a CI failure on NetBSD which looked like

    can't find package Expect
        while executing
    "package require Expect"
        (file "/usr/pkg/bin/unbuffer" line 6)

Rather than debug this, I just reimplemented unbuffer myself.  This also
reduces our test dependencies, which is nice.
