packetdrill: pull upstream fix for fno-common toolchains (#141574)
* 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
