Compilation flag D_XOPEN_SOURCE is causing failsafe to fail to
build when changing some DPDK libraries. The flag is not needed
and therefore is removed.

Gaetan, please approve that the flag is not needed.

I suspected popen or fgets from failsafe_args.c, but I wasn't able
to find a reason for the define. I can't remember the initial reason for
it, sorry.

I have tested the build on linux and freebsd, without issue, so at this
point I think this is ok.
