ebian, libbpf is pressent but doesn't
resolved as dependency by meson(may be pkg-config issues?).
On those systems qemu will be build without eBPF RSS steering.
The patch privedes changes for containers that able to build qemu
with libbpf: Alpine, Centos8 and Fedora.

The series of patches for eBPF RSS adds libbpf dependency for qemu.
https://lists.gnu.org/archive/html/qemu-devel/2021-03/msg08887.html
With this patch, libbpf added:
Alpine - added libbpf-dev
Centos 8 - added libbpf-devel
Fedora - added libbpf-devel

Basic idea is to use eBPF to calculate and steer packets in TAP.
RSS(Receive Side Scaling) is used to distribute network packets to guest
virtqueues
by calculating packet hash.
eBPF RSS allows us to use RSS with vhost TAP.
