+    configure: support systemd >= 209
+    
+    libsystemd-journal and libsystemd-daemon are now just
+    part of libsystemd.
+    
+    Keep original systemd checks as a fallback.
+    
+    Updates charon-systemd/Makefile.am accordingly.
+    
+    Tested on:
+    - debian wheezy (systemd v44)
+    - ubuntu 15.10 (systemd v255).
