vppinfra: remove linux/syscall.h
For portabiliy reasons it is better to have all wrapped in clib code. I.e. instead of using getcpu() we have clib_get_current_numa_node () and clib_get_current_cpu_id(). Type: refactor Change-Id: I29b52d7f29bc7f93873402c4070561f564b71c63 Signed-off-by: Damjan Marion <damarion@cisco.com>
