[PATCH 09/10] test: gstreamer: Include missing sanitizer/asan_interface.h header

[Kieran Bingham]

Quoting Laurent Pinchart (2024-06-24 20:29:40)
> The GStreamet tests define a __asan_default_options() function to

GStreamer

> influence the behaviour of ASan. The function is declared in
> sanitizer/asan_interface.h, but we don't include the header. This will
> cause missing declaration warnings when we enable the
> -Wmissing-declarations option.
> 
> Include the header to fix the issue. It can't be done unconditionally as
> not all toolchains provide ASan, so check for its availability at
> configuration time.

Ha, I just went looking to figure out where in meson this was defined,
but we create it!
