apparmor: LLVMLinux: Remove VLAIS
Replaced the use of a Variable Length Array In Struct (VLAIS) with a C99 compliant equivalent. This patch instead allocates the appropriate amount of memory using a char array using the SHASH_DESC_ON_STACK macro. The new code can be compiled with both gcc and clang.
