Postfix and IPv6

I discovered today that Postfix does not enable IPv6 for DragonFly.
It sets a FREEBSD4 macro based on 'uname' output for the build in
general, but it relies on compiler macros to enable IPv6 support and
has none for DF.

I worked around that with this patch:

Is simply checking for __DragonFly__ the best way to detect a
v6-capable DF host?  I assume there was never a v6-incapable version,
since we're based on FBSD 4, but I wanted to check before attempting
to submit this to the postfix project.
