Daniel Danzberger 4c50636912 unix: Fix linker errors when building without sdevent 
When building without systemd event support (-DLWS_WITH_SDEVENT=OFF) on
a system that has libsystemd headers installed, lib/plat/unix-systemd.c
is build in anyway.
The final libwebsockets library has then references to symbols from
libsystemd even though it won't be linked.

Resulting in the follwoing linker errros:
--
/usr/bin/ld: /usr/local/lib/libwebsockets.so: undefined reference to `sd_is_socket_inet'
/usr/bin/ld: /usr/local/lib/libwebsockets.so: undefined reference to `sd_is_socket_unix'
/usr/bin/ld: /usr/local/lib/libwebsockets.so: undefined reference to `sd_listen_fds'
--

This commit ensures that unix-system.c is only build when LWS_WITH_SDEVENT is set and
the system has libsystemd headers installed.
