* packetdrill: pull upstream fix for fno-common toolchains
Example toolchain is clang-12. The patch fixes the following
build failure:
$ nix-build -E 'with import ./. {}; packetdrill.override { stdenv = clang12Stdenv; }'
...
ld: libpacketdrill-lib.a(tcp_options_to_string.c.o):(.bss+0x0):
multiple definition of `tcp_option';
libpacketdrill-lib.a(run.c.o):(.bss+0x18): first defined here
