test: v4l2_compat: Disable test when ASan is enabled
The V4L2 compat test runs v4l2-ctl and v4l2-compliance with v4l2-compat.so preloaded. If libcamera is compiled with the address sanitizer enabled, the ASan library will be loaded due to preloading v4l2-compat.so. This however doesn't occur early enough in the dynamic linking process due to the v4l2 executables not being themselves linked to the ASan runtime, which causes ASan to abort with ==2198==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD. Using LD_PRELOAD to load the ASan runtime would fix this issue, but it requires knowing the absolute path to the ASan shared object. This is compiler-dependent and for clang, architecture-dependent as well. Until we figure out how to safely retrieve that information, disable the test when ASan is enabled as a quick fix.
