Subject: alpha: uapi: Add support for __SANE_USERSPACE_TYPES__

From: Ben Hutchings <ben@decadent.org.uk>

commit cec80d82142ab25c71eee24b529cfeaf17c43062 upstream.

This fixes compiler errors in perf such as:

tests/attr.c: In function 'store_event':
tests/attr.c:66:27: error: format '%llu' expects argument of type 'long long unsigned int', but argument 6 has type '__u64 {aka long unsigned int}' [-Werror=format=]
  snprintf(path, PATH_MAX, "%s/event-%d-%llu-%d", dir,
                           ^
