core: use syscall wrappers instead of direct syscalls - tail

tail, as in dog chasing its tail. These are the unwrapped
syscalls that have crept in (or were missed) in the previous
patches.

various xlators and other components are invoking system calls
directly instead of using the libglusterfs/syscall.[ch] wrappers.

If not using the system call wrappers there should be a comment
in the source explaining why the wrapper isn't used.
