Make ayatana-appindicator dependency optionalHEADmaster

The wlrandr plugin hard-linked ayatana-appindicator3, making it
a mandatory requirement of Wayland builds. This patch adds an
--enable-appindicator configure option to make sure Wayland support is
no longer silently disabled when appindicator is missing.

Fixes #442
