[PATCH wayland] scanner: Correct doxygen group name for *_add_listener

[Yong Bakos]

From: Yong Bakos <ybakos at humanoriented.com>

From: Bill Spitzak <spitzak at gmail.com>

Scanner has been generating the doxygen group label "foo_iface" for all
*_add_listener functions, and the label "iface_foo" everywhere else.

Correct the label generation, so all *_add_listener functions appear correctly
within doxygen output.

See: https://patchwork.freedesktop.org/patch/89806/
