tiny: make dbus, openssl, and notifications each optional

This commit exposes support for compilation without dbus, controlled
by the global dbusSupport argument.  This argument is understood by
many other nixpkgs expressions and can be set globally in
~/.config/nixpkgs/config.nix.

This commit also adds two package-specific arguments:

* notificationsSupport allows to disable the desktop-notifications
  feature when invoking cargo.

* useOpenSSL can be set to false in order to compile tiny with rustls
  instead of openssl.
