libsanitizer, darwin: Unsupport Darwin >= 22 for now.

Browse Source 
The mechanism for location dyld has altered from Darwin22 since dyld is now
in the shared cache.  The implemented mechanism for walking the cache uses
Apple Blocks which GCC does not yet support, and the fallback to the original
mechanism does not work there.

Until a suitable work-around can be found, unsupport Darwin22+.

libsanitizer/ChangeLog:

	* configure.tgt: Unsupport Darwin22+ until a mechanism can be found
	to locate dyld in the shared cache.
