Fix SSL support for evolution-data-server

[walt]

The pkgsrc version of evolution doesn't support SSL on DragonFly
because the 'configure' script in evolution-data-server is broken.

The patch below is a drop-in replacement for patch-ak in the
evolution-data-server package.

The problem it fixes:
The configure script uses PTHREAD_LIB before it is initialized,
so the test for NSS (NetScape Secure Sockets) fails on DFly.

Needed to have a NULL macro in the program that follows these includes.
