add preadv2 and pwritev2 syscall numbers for linux v4.6

the syscalls take an additional flag argument, they were added in commit
f17d8b35452cab31a70d224964cd583fb2845449 and a RWF_HIPRI priority hint
flag was added to linux/fs.h in 97be7ebe53915af504fb491fb99f064c7cf3cb09.

the syscall is not allocated for microblaze and sh yet.
