test: gstreamer: Add test for gstreamer single stream

This patch adds a test to test if single stream using libcamera's
gstreamer element works.

We need to work around two distinct issues with ASan when enabled in the
build:

- glib has a known leak at initialization time. This is covered by the
  suppression file shipped with glib, but it's not clear how to use it
  automatically. For now, disable leak detection to avoid test failures.

- GStreamer spawns a child process to scan plugins. If GStreamer is
  compiled without ASan (which is likely) but libcamera is, dlopen()ing
  the libcamera plugin will cause an ASan link order verification
  failure. Disable the verification child processes to work around the
  problem. This requires gcc 8 or newer.
