  tmux.conf: detect running as tmate and disable non-supported features

tmux versions >=2.3 support the -q option for source-file to suppress
errors for nonexistent files. Even Debian/oldoldstable has tmux v2.3-4,
so this works nice everwhere, *except* for when invoking tmate, which is
a fork based on an old version of tmux, which then complains about:

| /etc/tmux.conf:75: usage: source-file path
| /etc/tmux.conf:36: usage: source-file path

Try to detect tmate from within the environment, and then enable
the configuration only when *not* running from within tmate.
