Fix detection of setres*id on GNU/Hurd
Like Linux, proper _SOURCE macros need to be set to get declarations of
various standard functions, notably setres*id. Now that Debian is using
-Werror=implicit-function-declaration this is really required. While at
it, define other _SOURCE macros like on GNU/Linux, since GNU/Hurd uses
the same glibc.
