ASL_CACHE_INFO: Replace 1-element array with flexible array

Similar to commit 7ba2f3d91a32 ("Replace one-element array with
flexible-array"), replace the 1-element array with a proper
flexible array member as defined by C99. This allows the code to
operate without tripping compile-time and run-time bounds checkers
(e.g. via __builtin_object_size(), -fsanitize=bounds, and/or
-fstrict-flex-arrays=3).

One binary difference appears in aslcache.o, which appears to be the
compiler choosing different working registers. No other changes are seen
in the .text nor .data sections.
