Subject: [PATCH] bpf: disable -fstack-protector in meson

In Gentoo, we recently started making Clang behave the same way as
our GCC, with -fstack-protector and some friends enabled by default.

SSP doesn't make sense for BPF, so disable it explicitly.

See also e.g. https://www.spinics.net/lists/netdev/msg556400.html.
