cmake: Fix definition of DBUS_USE_SYNC

Browse source 
dbus-sysdeps-unix.c checks for DBUS_USE_SYNC using 0/1 checks not defined
checks, so we should be using #cmakedefine01. This fixes lots of -Wundef
warnings when compiling for FreeBSD and ensures that we actually use
atomics instead of the pthread fallback there.

(cherry picked from commit b932c343c4)
