There is a common macro __rte_aligned for alignment,
which is now used where appropriate for consistency.

This commit adds eBPF system call definitions for ARM architecture.
Old Linux header files may not define eBPF system call numbers.
In order to successful compile eBPF on all Linux platforms - the
missing ARM system call definition is explicitly added.

This patch defines __NR_bpf for powerpc architecture and hence,
fixes compiling tap driver for this architecture.

eBPF has a graceful approach: it must successfully compile on all Linux
distributions. If a specific kernel cannot support eBPF it will gracefully
refuse the eBPF netlink message sent to it.
The kernel header file linux/bpf.h (if present) on different Linux
distributions may not include all definitions required for TAP
compilation.
In order to guarantee a successful eBPF compilation everywhere all the
required definitions for TAP have been locally added instead of including
file <linux/bpf.h>
