pathmtu/pathmtu.c: Don't explicitly set `_BSD_SOURCE'.

I have a bit set that this was necessary for some reason, but it doesn't
seem to be based on a brief inspection of wheezy's <features.h>, and
stretch's version warns that `_BSD_SOURCE' is now deprecated, because
nothing is allowed to remain stable.
