test: gstreamer: Include missing sanitizer/asan_interface.h header

The GStreamer tests define a __asan_default_options() function to
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.
