net/tap: fix build on ARM32

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.

Fixes: b02d85e1 ("net/tap: add eBPF API")
