tell ubsan to ignore SUN_LEN
ubsan will report undefined behavior due to the SUN_LEN macros interaction with a null pointer, so let's tell ubsan to ignore this function. After carefully reviewing the final publically availlable drafts of the C99,C11 and C18 standards I can confirm that dereferencing null pointers is still undefined behavior, as such ubsan will always warn with absolutely every existing compiler version. Since the sanitizers are periodically synced between llvm and gcc I'm also fairly confident that rebuilding everything with compiler_rt to use the integrated sanitizers would result in the same message. I sincerly hope that this explanation provides to be sufficient, If not I'd be willing to show up at the next llvm dev meeting to provide quotes from actual sanitizer developers to back up these claims.
